| - | The ACS-SASSI interface with the [[ :legal|ANSYS ]](r) Workbench(tm) uses a small subset of elements available to the user of the Workbench(tm) software. The ANSYS(r) file converter will take a Model in the .cdb file format and converts the data to a model that is usable by the [[ SASSI:Submodeler ]]. The converter only converts a small subset of ANSYS(r) elements and the way that these elements are converted does not cover the full spectrum of how these elements may be defined by ANSYS(r). The limitations below are for models that can be converted to run under SASSI. If a particular option is not discussed it is not supported in the converter the model will likely convert the model but be converted model will be incorrect. Any variance from these instructions will either cause an error in conversion or yield an incorrect model when conversion is complete. | + | The ACS-SASSI interface with the ANSYS ® Workbench™ uses a small subset of elements available to the user of the Workbench™ software.

| - | Newer versions of the fast solver have the ability to take matrices directly from ANSYS(r) and use them in simulation. This converter will convert the model that can be displayed in the Submodeler, but these model will be flagged Submodeler and the files that the [[com:AFWRITE]] generates will not be runnable using the traditional methodology. If the model isn't runnable the user will receive a warning when the file is converted. The list of elements types below are the additional element types that can be converted for a display model. There are no limitations on these elements because only element node connections need to be translated for display. Other elements will be ignored by the converter and not be included in the model.
