WARNING: Only n% of surfaces have been meshed!Additional meshing may be required to display other views of this solution.The file <(><<)>file name>.shp will be required for additional meshing.Saved rendering database to <(><<)>path to design file>\<(><<)>name of file>.ptdThis message is appearing in Message Center when saving Particle Trace Solution to file.
Disable "Visible Surfaces Only".This simply means that the current Particle Trace solution is not a complete rendering solution for the whole model.This is caused by processing a solution while "Visible Surfaces Only" in the Particle Trace settings is enabled.Steps to correct (if the need to render all surfaces is wanted):1. Go to Settings > Rendering > Particle Trace2. Go to the Meshing section.3. Disable "Visible Surfaces Only".4. Recalculate solution.
