  1. Hello, as suggested in another thread in this Forum, i tried the usage of dresp3-Card. What i want to do: - let excel calculate the tresca-stress (Input: max principle, min principle, output: stress (=difference between both input variables). - get the tresca stress back and use it for an "minmax-" or "min-objective" in optimisation What i wrote until today: LOADLIB DRESP3 GR01 tresca.xlsx $solid DRESP1 1 MAX_PR1 STRESS PSOLID SMAP DRESP1 1 MAX_PR3 STRESS PSOLID SMIP DRESP3 20 TRESCA GR01 MYFUNC 1 2 + DRESP1 1 2 + CELLIN C2 C3 + CELOUT D1 I also use a small excel-file, which calculates the difference beween "cell C2" and "cell C3" in "cell D1". Questions: - would it work like that ? (I can't test it at the moment) - What do I get with the DRESP1 / DRESP3 ? When using DRESP1 with "ELEM" and enter an element-ID, it would give ONE value to the excel-file, which seems to be pretty clear. But when I use PSOLID as the PTYPE, there might be hundrets or thousands of values (here: principal stresses). At that point I do not understand my own programmed code.. Maybe someone can help? I read the Tutorial OS-4095 and also a lot of manual pages. Thanks a lot
  2. Hello, If I am to put RBE3 in a hole (with no force or constraint attached to the dependant node) will this imply any stiffness to the voids outer surface where the independent nodes are? Or does the hole just remain as it would if it was a void with nothing in it? What type of 1D element could be used to provide a defined stiffness to the outer surface of a hole? Thank you in advance
