STRAIGHTFORWARD AND FASTER ANALYSISComplement challenging physical experiments by efficient simulations even on micro- and nanoscale samples:• simply provide a few parameters about the material• obtain simulation results directly and faster• easily modify simulation parameters for swift reruns

TIME AND RESOURCE-SAVING SIMULATIONS

Xlab solvers do not require demanding conversions to geometric models, unlike geometry-based simulations:• equations are solved using the time and resource-saving finite-

volume method• no software switching, no data file export and import anymore!

image processing, simulation and analysis are fully integrated features.

ALL-IN-ONE VIRTUAL MATERIALS CHARACTERIZATION LAB

integrated with avizo fire, Xlab simulation solvers provide a comprehensive digital lab for materials characterization:• Powerful 3d image processing and segmentation• extensive quantification analysis tools• direct intrinsic material properties calculation• gPu-enabled computation• easy comparison of simulation results vs. images from experiment• Connection of custom algorithms to avizo• High-end 3d visualization

COMPUTE PROPERTIES USING TWO APPROACHES

CoMpuTATIoN oF ThE INTRINSIC TENSoRthe continuum equations are derived using general methods such as volume averaging or homogenization. these methods are developed under strong mathematical and physical assumptions, and provide a way of predicting a tensor of the intrinsic property. they require imposing periodic boundar y conditions on a representative elementary volume and solving equations which are close to the continuum ones.the resulting tensor provides the effective property of a representative sample along the different directions.

SIMuLATIoN oF AN EXpERIMENTan experiment is simulated by generating a constant disequilibrium between two opposite faces of the sample. the other faces are hermetically closed. the equations are solved and the resulting field is used to estimate the material property.

RUN FAST ITERATIVE SIMULATIONS

Gpu ACCELERATIoNsolving the system of equations for a numerical model of material properties is very compute-intensive. the gPu implementation of Xlab algorithms* considerably increases the computing speed, making Xlab solvers extremely efficient tools for the numerical simulation of material properties. the powerful gPus that usually equip workstations on which avizo and Xlab run are thus optimally used, allowing users to perform multiple simulations in record time.
