ANSA is a powerful pre-processing software from BETA CAE systems. Using the Task Manager, ANSA provides an interface for you to set up an optimization task and define optimization parameters (for example, thicknesses), material parameters, or control variables for shape morphing (see ANSA tutorials for further information). ANSA is reading and writing a DV file to interface with any third party optimizer.

After selecting the DV file from the ANSA input node, all parameters defined in the ANSA task manager can be registered as optiSLang parameters or input slots using drag and drop. If the input node is connected to a parametric system, the range information provided by the DV file is used to define the initial parameter limits for any variation study in optiSLang.

Expected File Content

The input DV file is a machine readable ASCII file, see the following example for reference.
