Currently Workbench is not taking Parasolid file through import option in ANSYS Student V 18.2. Highlighted error in ANSYS Meshing is shown below:
Workaround: You need to import the file in Design Modeler (DM) first and then proceed for meshing.
Hopefully we will fix this bug in our upcoming version soon.
Thanks & Regards,
