#### Combine analyses in a single, integrated project

GeoStudio enables you to combine analyses using different products into a single modeling project, using the results from one as the starting point for another.

#### Define geometry using drawing tools or importing CAD files

GeoStudio provides the tools to define model domain including coordinate import, copy-paste geometric items, length and angle feedback, region merge & split, and direct data entry.

#### Efficient, parallel solving of project analyses

GeoStudio runs each analysis solver in parallel, allowing multiple analyses to be solved efficiently on computers with modern, multi-core processors.

#### Interpret results with visualization & graphics

GeoStudio provides powerful visualization tools, including graphing, contour plots, isolines, animations, interactive data queries and data exports to spreadsheets for further analysis.

### How SLOPE/W works with other GeoStudio products

**Use pore-water pressures from SEEP/W, SIGMA/W, QUAKE/W or VADOSE/W**

Using finite element computed pore-water pressures in SLOPE/W makes it possible to deal with highly irregular saturated/unsaturated conditions or transient pore-water pressure conditions in a stability analysis. For example, you can analyze changes in stability as the pore-water pressure changes with time.

**Use stresses from SIGMA/W or QUAKE/W**

### How SEEP/W works with other GeoStudio products

**Dissipate excess pore-water pressures generated by SIGMA/W or QUAKE/W**

Excess pore-water pressures generated by static loading (e.g. fill placement) or by dynamic motion during an earthquake can be brought into SEEP/W to study how long it takes to dissipate the excess pressures.

**Use SEEP/W pore-water pressures in SLOPE/W**

Using finite element computed pore-water pressures in SLOPE/W makes it possible to deal with highly irregular saturated / unsaturated conditions or transient pore-water pressure conditions in a stability analysis. For example, you can analyze changes in stability as the pore-water pressure changes with time.

**Use SEEP/W data inside a CTRAN/W model for contaminant transport or a TEMP/W model for convective heat transfer analysis.**

### How SIGMA/W works with other GeoStudio products

**Use SIGMA/W stresses in SLOPE/W or QUAKE/W**

Using finite element computed stresses in SLOPE/W makes it possible to conduct a rigorous stability analysis using the same stress values resulting from the deformation analysis. In addition, you can use SIGMA/W stresses as the initial stress state for a dynamic earthquake analysis in QUAKE/W.

**Use SIGMA/W pore-water pressures in SLOPE/W or SEEP/W**

### How QUAKE/W works with other GeoStudio products

**Use QUAKE/W results in a SLOPE/W stability analysis**

Earthquake shaking of ground structures creates inertial forces that may affect the stability of the structures. The shaking may also generate excess pore-water pressures. Both the dynamic stress conditions and the generated pore-water pressures can be taken into SLOPE/W to study how an earthquake affects the earth structure stability and deformation. SLOPE/W can perform a Newmark-type of deformation analysis to determine the yield acceleration and estimate the permanent deformation of the earth structure.

**Dissipate excess QUAKE/W pore-water pressures in SEEP/W**

Excess pore-water pressures generated during an earthquake can be brought into SEEP/W to study how long it will take to dissipate them.

### How TEMP/W works with other GeoStudio products

Measured climate data can be pasted from a spreadsheet into TEMP/W and used to determine the actual ground surface temperatures with or without snowpack. TEMP/W will use precipitation data to accumulate snow depths over the winter. An energy balance approach is used to calculate ground temperatures beneath snow and to melt snow during the spring. Link it with SEEP/W or AIR/W for convective heat transfer analysis.

### How CTRAN/W works with other GeoStudio products

**Use SEEP/W or VADOSE/W Velocities in CTRAN/W**

One of the major components in a contaminant transport analysis is the velocity of the water, which can be obtained from a SEEP/W or VADOSE/W analysis. Once this velocity is known, it can be used in CTRAN/W to study the transport of contaminants.

**Perform Density Dependent Analyses with CTRAN/W and SEEP/W**

In density dependent fluid flow, the velocity of the water is dependent on the solute concentration. The water velocity in turn influences the movement of the solute. The iterative transfer of water velocity from SEEP/W to CTRAN/W and the transfer of concentration from CTRAN/W to SEEP/W makes it possible to do density dependant fluid flow analyses.

### How AIR/W works with other GeoStudio products

**Use AIR/W data in TEMP/W**

### How VADOSE/W works with other GeoStudio products

**Use VADOSE/W pore-water pressures in SLOPE/W**

Use QUAKE/W to consider dynamic loading on the structure due to an earthquake. QUAKE/W can begin with the initial stress and PWP profile that has already been computed by SIGMA/W and SEEP/W and then apply earthquake accelerations to model the resulting changes stress. A Newmark analysis can be conducted in SLOPE/W to determine the cumulative displacement along the critical slip surface.

### SLOPE/W

SLOPE/W is the leading slope stability software for computing the factor of safety of earth and rock slopes. SLOPE/W can effectively analyze both simple and complex problems for a variety of slip surface shapes, pore-water pressure conditions, soil properties, analysis methods and loading conditions.

### SEEP/W

SEEP/W analyzes groundwater flow within porous materials such as soil and rock. Its formulation enables analyses ranging from simple saturated steady-state problems to sophisticated saturated/unsaturated time-dependent problems.

### SIGMA/W

SIGMA/W performs stress and deformation analyses of geotechnical, civil and mining works. It can perform a simple linear elastic deformation analysis or a highly sophisticated soil-structure interaction analysis with non-linear material models and coupling to seepage analysis.

### QUAKE/W

QUAKE/W enables dynamic analysis of earth structures subjected to earthquake shaking, or point dynamic forces from a blast or a sudden impact load. It determines the motion and excess pore-water pressures that arise due to shaking.

### TEMP/W

TEMP/W enables analysis of thermal changes in the ground due to environmental factors or the construction of facilities such as buildings or pipelines. TEMP/W can be applied to the geothermal analysis and design of geotechnical, civil, and mining engineering projects.

### CTRAN/W

CTRAN/W models the movement of contaminants through porous materials such as soil and rock. CTRAN/W can be used to model simple diffusion-dominated systems through to complex advection-dispersion systems with first-order reactions.

### AIR/W

AIR/W analyzes groundwater-air interaction problems within porous materials such as soil and rock. It enables analyses ranging from simple, single-phase air-transfer analyses to complex coupled air-water systems.

### VADOSE/W

VADOSE/W analyzes interactions at the ground surface to determine environmental impacts on the movement of water through the unsaturated vadose zone and into the local groundwater regime. Potential interactions considered in VADOSE/W include infiltration due to rainfall and snowmelt, root transpiration, gas diffusion, and surface runoff, evaporation and ponding.
