Export modules

Export modules allow to export computed data into external software for post-processing. The number of export module records is specified in analysis record using nmodules parameter (see section 6). The general format is following

*EntType	[tstep_all]
	[tstep_step(in) #]
	[tsteps_out(rl) #]
	[domain_all]
	[domain_mask(in) #]

To select all solution steps, in which output will be performed, use tstep_all. To select each tstep_step-nth step, use tstep_step parameter. In order to select only specific solution steps, the tsteps_out list can be specified, supplying solution step number list in which output will be done. To select output for all domain of the problem the domain_all keyword can be used. To select only specific domains, domain_mask array can be used, where the values of the array specify the domain numbers to be exported. Currently, the supported export modules are following

• VTK export

  vtk	[vars(ia) #]
  	[primvars(ia) #]
  	[stype(in) #]
  	[regionstoskip(ia) #]

  
  

  The array vars contains identifiers for those internal variables which are to be exported. The id values are defined by InternalStateType enumeration, which is defined in include file ``src/oofemlib/internalstatetype.h''. The array primvars contains identifiers of primary variables to be exported. The possible values correspond to the values of enumerated type UnknownType, which is again defined in ``src/oofemlib/unknowntype.h''. Please note, that the values corresponding to enumerated type values start from zero, if not specified directly and that not all values are supported by particular material model or analysis type. The parameter stype allows to select smoothing procedure for internal variables, which is used to compute nodal values from values in integration points. When vtk is configured to operate in region-by-region mode (the default), then the export is done on region by region basis. In this case, the smoothing is performed only over particular region, where only elements in this region participate. Then the regionstoskip parameter allows to skip given regions when generating output, so only remaining regions (and corresponding elements and nodes) will be exported.
