  1. Here you have it Thanks! Carro_con_topes_y_guias.hm fem.fem
  2. Hi! I'm trying to mesh a solid with TetraMesh and it states the following error: "2 edges failed nodal setup. Meshing failed". But I can't see anything wrong or red colored or anything that tells me where the mistake is. Even with visualisation options. The solid is created properly with bounding surfaces so I guess there are not free edges. Could you help me?
  3. Good morning, I'm running a transient analysis of 2 gears (one of them with a preload and the other one with an imposed rotation). When I run it with Optistruct I get 2 problems: *** ERROR # 4965 *** Maximum number of time increment cutbacks reached, analysis aborted. The biggest problem comes here, if I analysis the results, the contact status is 0 everytime. The gears rotate but they don't seem to have a good contact. Moreover, I get high normal contact forces at points where there should be any contact (see image attached). I also attach the .fem to make it quicker and the .out from the previous simulation Thanks!! 1107rem.out 1207manana.fem

  5. The goal is to measure the transmission error. I already did (some months ago) a quasi-static analysis. Now I want to do it transient, dynamic so I have to change the way I apply the rotation. (In the quasi-static I did it using SPC).
  6. Thanks! But how do I create the motion of the wheel rotating? Would that be a transient analysis?
  7. Hi! I wanna model the rotation of a gear (wheel) with a preload in the pinion. I asume the preload is modeled with a moment but, how do I model the rotation? And which analysis type should I choose? (I don't want a quasi-static one). Some analysis don't let me include a LOAD. Thanks in advance!

  10. Problem solved. Anyway, I still don't manage to get what I needed
  11. I guess I have to créate a curve first but I get this error when I click "new" on "curve editor" while executing "hm_getstring "Name =" "Create a new curve"" (procedure "::HMCurveEditor::onNewCurve" line 6) invoked from within "::HMCurveEditor::onNewCurve" ("eval" body line 1) invoked from within "# Compiled -- no source code available error "called a copy of a compiled script"" (procedure "::hwt::ReleaseCanvasButton" line 1) invoked from within "::hwt::ReleaseCanvasButton 0 .ceWindow.actionFrame.newButton" (command bound to event)
  12. I have no idea of how to create a constant velocity on the rueda and a ramping up moment on the pinion
  13. Yep 200.000 N·mm (200 N·m)
  14. Is it necessary to change all the loads as u did? The "rueda" was supposed to be rotating some degrees during each step (quasi-estatic analysis), while the pinon had a moment. Why are all the noded from rueda and pinon blocked in all DOF but the rotation in Z? Can't the moment be applied as it was before (you created a curve to do it) Thanks a lot and sorry for so many problems,
