Keyword type: step
This option allows for (a) the specification of section stresses on the boundary of submodels, cf. the *SUBMODEL card and (b) the application of a pressure on a facial surface.
For submodels there are two required parameters: SUBMODEL and either STEP or DATA SET. Underneath the *DSLOAD card faces are listed for which a section stress will be calculated by interpolation from the global model. To this end these faces have to be part of a *SUBMODEL card, TYPE=SURFACE. The latter card also lists the name of the global model results file.
In case the global calculation was a *STATIC calculation the STEP parameter specifies the step in the global model which will be used for the interpolation. If results for more than one increment within the step are stored, the last increment is taken.
In case the global calculation was a *FREQUENCY calculation the DATA SET parameter specifies the mode in the global model which will be used for the interpolation. It is the number preceding the string MODAL in the .frd-file and it corresponds to the dataset number if viewing the .frd-file with CalculiX GraphiX. Notice that the global frequency calculation is not allowed to contain preloading nor cyclic symmetry.
The distributed load type label convention is the same as for the *DLOAD card. Notice that
For the application of a pressure on a facial surface there is one optional parameter AMPLITUDE specifying the name of the amplitude by which the pressure is to be multiplied (cf. *AMPLITUDE). The load label for pressure is P.
If more than one *DSLOAD card occurs in the input deck, or a *DLOAD and at least one *DSLOAD card, the rules explained underneath the keyword *DLOAD also apply here.

specifies hat on face 3 of all elements belonging to set Se1 the section stress is to be determined by interpolation from step 4 in the global model.
