Starting in Release 2019 R1, Distributed Solve is the default: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v193/ai_rn/rnmapdlupdateguide.html%23d0e4041 Typically, what happens is that, after you solve, the results are read into memory at the end of the solution. (For SMP version, this behavior can be overridden with /CONFIG,NOELDB,1.) Distributed Solve, however, acts differently in this respect from SMP version. (Note in /CONFIG documentation, NOELDB has no effect with Distributed Solve as noted in the “Notes” section.) Thus, in 19.2 and prior, the SMP version was used, which loaded the entire last result set after solution. However, in Release 2019 R1, the DOF solution is loaded but not everything else, so the SET command is needed to read results from the result file. Results such as EF (in Electromagnetics) are derived results, not DOF results, hence VOLT can be post-processed right away without the SET command but EF needs to be read from result file first. In general, it’s good practice to always load the result set you want with the SET command.
