  1. Sir, By default, in measures I see dynamic mim/max option to see deformation of nodes having min/max deformation magnitude at the LAST STEP of simulation which can show their deformation values progressively with the simulation steps. However, how can I get the dynamic deformation values of particular node of interest, no matter whether it is having maximum or minimum overall deformation?
  2. Hello, in my analysis of a curve-drive-part is a rotation as SPC, solids for the curve-part (red) and a rigid-spider (blue) to transfer the rotation displacement to the solids. I use an NLGEOM-analysis, because i want to simulate the contact between the other parts (not in picture) and the curve-part. In this analysis the curve-part shows a strange deformation and the contact force is going very high. There is no constraint or force, that explained the deformation. Attached filses: Topf_Start_1 - front view with a distance measure of 211.666 Topf_Start_2 - side view Topf_End_1 - front with a distance measure of 201.110 Topf_End_2 - side view It is a model in optistruct, but for the solving is radioss used, because the large sliding contact. I want to understand possibly failures in the model. greetings Pierre
  3. Hi All Trying to run an Optistruct analysis to see how two layers of different materials will displace when experiencing a thermal load. In my case I have chosen points along a lattic where the temperature would be 80degC. But when running my model in Optistruct and in trying to view the results, the model cannot show a viable solution or a solution that makes sense, in fact, I have not setup the pre processing properly (it seems) which has lead to a model with massive deformation. Also I am unable to view the contours. The attached picture shows circled areas (red) where I have made equivalence nodes, there is an expected connection at these points (not defined). Hoping that anyone could give advice or guidance! Phil Busbar Copper Lattice Model 2D.fem Busbar Copper Lattice Model 2D.mvw
  4. Hello guys, I studding the deformation of a structure (plane) in HyperMesh (with the Optistruct tool ), so after having the deformation in HyperView I want to export is to Feko to do an electromagnetic simulation. How can I do the exportation from HyperView to Feko? And witch extension type of file I have to export from HyperView to Feko to have a geometry in Feko and not a mesh. Here you have the "*.hm" file that I am studying attached. Thank you for your help. Regards, Samir. direct_response_flat_plate.hm
  5. I ran a simulation with a non linear material ( Having a stress strain curve data upto its ultimate tensile stress). In the simulation results, the von mises stress exceeds the limit of stress I have entered in the curve data. What is happening here? Is the software extrapolating from the data OR assuming zero resistance from the regions where the von mises stress has exceeded the ultimate limit.
  6. Hello, I would like to simulate a void as a region within my model that should not experience any deformation - to not damage any structure that may be place there e.g. a bearing. This is to be for a topology optimisation simulation, then how (if it is possible) can it be approached so that the optimal topology maintains the shape of the void? To expand, if I have a circular hole where a bearing should be placed and I do not want the deformation of the model to damage this bearing, how can I contrain the hole to maintain its shape during the topology optimisation? I would not like to use RBE2s or a nondesign space as this will effect the way the load paths are transferred. Will RBE3s work? If not, is there an alternative? Thank you in advance.
  7. How can you control the amount of deformation with SurfDrape? It's doing a loose deformation, taking each object control point and doing a move transformation from the base UV to the target UV. A single span curve remains a single span curve. How can I achieve zero deformation? I only want a move/rotate transformation on the object's local axis is moved and rotated from it's base UV to the target UV. Or a full deformation, where the objects path on the base UVs are used to interpolate a much more complex object on the target?
