when i try to reopen my past results, i get the following message :"This plot refers to the features which do not exist anymore or have lost their attributes. PLease select them again " (in the image)
initially, after loading the flow simulation addin, when i open the model, i get the red 'X' mark on the boundary conditions. these gets cleared as the results files were loaded into the simulation and still, i'm not been able to view the results. also, the face selected in defining the boundary conditions were lost. why does this happens and how to solve this....please enlighten me on this problem..
sounds like your model changed after you ran the analysis
therefore those faces no longer exist or were rebuild and designators reassigned in solidworks
or you have a model with some issues that cause the above type problems
make sure you're managing your configurations well, that your assembly is clean or work with separate assemblies if you continue having trouble.
if you want to check the software, setup a simple pipeflow problem and see if the problem reproduces itself.
