I hope someone can help me or confirm my difficulties with the FEM postprocessor. I create a ResultPipeline with Mode Surface with Edges and a Field by Mises Stress for instance . Then I create a datapoint with a field of Mises stress and suddenly the legend is only visible with one value and also erroneously retrievable with this value. With version 0.18-16110 (git) this was partially fixed by selecting ResultPipeline again with the respective options. In addition, sometimes one could directly enter and evaluate the x, y, z when selecting the point under Datapoint. For me it is serious with version 0.19 that under tension the principal stresses are no longer available. In my opinion, these are important for many failure hypotheses. I hope that this will feed into the development, then for me the post-processor is a very good help.
