Arbitrary Analysis Sequence

Multiple analysis may be made using the FEM_INPUT command in Tosca Structure parameter file. The results of all finite element calculations are summarized in one Tosca Structure result file with each finite element calculation being interpreted as a single load case.

In FEM_INPUT command, multiple finite element input files may be specified using the parameter FILE. Example:

FEM_INPUT
 FILE = static_analysis.dat
 FILE = modal_analysis.dat
END_

Instead of performing only one finite element analysis, Tosca Structure automatically runs multiple finite element analyses in the order of FILE = ... parameters in FEM_INPUT. In the example above, first the static analysis and then the modal analysis are performed.

Note, that:

  • The model information of the different input files (nodes, elements, groups) has to be identical. The loads may be different for the different input files.
  • The modifications of the geometry that occur during the optimization are applied to all input files at once.
