Ansys Workbench uses ds.dat files to transfer data to Ansys Mechanical. These files contain APDL commands that describe and set up the numerical problem to be solved. oSP3D is using the same mechanism to generate random fields. You need only to input the oSP3D-generated DAT file before your solution step in Ansys Mechanical. You must include this DAT file after the creation of the mesh. Otherwise, Ansys Mechanical replaces the node coordinates that oSP3D exported with its predefined definition.
oSP3D always rewrites the DAT file, ignoring its original contents. oSP3D can use DAT files to export the following data to Ansys Mechanical:
Node coordinates: x, y, z
Node coordinate deviations (with respect to the reference mesh): x, y, z, normal
You can use this command to import the DAT file:
/input,../../sos_output.dat
The DAT file already switches into /PREP7 mode.
