Re: ccxInputWriter vs. Faces

See http://www.dhondt.de/ccx_2.12.pdf Page 282 cit: For shell elements no face number is needed since there is only one kind of loading: pressure in the direction of the normal on the shell. Applying a pressure to a face for which a pressure was specified in a previous step replaces this pressure. P...

Re: Why does my loft kiink?

I think it's not forbidden to use more than one sketch for sweeping. Especially if you need more control of twisting profiles. I simply not understand your global coord. system. :( Which faces should stay vertical? Is this what you expect? handrail untwisted.FCStd handrail topview.png Another exampl...

Re: Why are arc segments not twisted during sweep?

I think you only moved the ARC for the sweep from the center of the arc in the sketch 15 mm downwards to the bottom of the shape That's right. In SALOME one can see results immediately after checking offered boxes, of course if "preview" is checked too. If box "With contact" is checked both sketche...

Failed on enumerating of Faces

Hello, there seems to be an issue, if more than one FemPressureConstrain object is used. This is a box made from shells. There is one pressure object with two loads inside. 1 FemConstrainPressureObj with 2 loads.png Result doesn't look so bad, despite faulty load/deflection directions (but that's an...
