Overview

Some file name conventions are explained within this section.

Solver type

Tosca Structure supported input

Tosca Structure supported output

Abaqus

.inp

.fil or .sim (see below)

.odb

Tosca Structure supported file formats for Abaqus. See also the flow diagram in Overview.

All FE input models (.inp) and FE results (.odb, .fil or .sim) are moved into their corresponding SAVE directory.

Abaqus must always be called in interactive mode within Tosca Structure. Thus, using Abaqus in background mode is not allowed.

It is highly recommended that you use the same main versions of Tosca and Abaqus. Versions of Abaqus later than 2023 are not supported by this release of Tosca. Earlier releases of Abaqus can be used with Tosca with the following restrictions:

  • SENS_CALC_MODE=SOLVER is supported only if the main releases of Abaqus and Tosca match. It is highly recommended that you also use the same Hot Fix version.
  • Using MatrixFormats.SIM in sensitivity-based calculations with SENS_CALC_MODE=TOSCA is supported only if the main releases of Abaqus and Tosca match. It is highly recommended that you also use the same Hot Fix version. If the versions do not match, MatrixFormats.FIL might work as a workaround but full functionality cannot be guaranteed.
