When trying to use submodeling in Workbench with an .rst file created by a solve that was done totally in MAPDL and map the results across why one gets a ‘General Error’?

      The workflow uses External model to read in the .cdb file and then Tools>Read Results in Mechanical to read the results in to Mechanical. A dummy command object under the Static Structural branch will be needed in order to ‘trick’ Mechanical into showing up as complete. For submodelling to work the .rst file will need to contain the information about the units used during the solve. For models solved from Mechanical the /UNITS command is used to record this information. By default models set up in MAPDL from scratch will not include this. This will lead to a message something similar to this “Since the result file does not indicate the unit system, the following file unit system is assumed: Metric (m, kg, N, s, V, A)” This will then lead to the ‘General Error’ when the results are mapped across. In order to overcome this one can resume the database in MAPDL, read in the results set of interest and then issue /UNITS to define the set of units used. Then use the RESWRITE to recreate the existing results set onto a new file with the units recorded. Note the SI and User cannot be used on the /UNITS command for this to work. Everything else is fine.
