      Dear Users Our Commercial and Academic users around the world can use these same forums here as before i.e. the Altair Support Forum , Commercial users from India with solver queries can go to the Solver Forum for India Commercial Users , Academic Users from India and AOC India Participants are requested to go to the Forum for India Academic Users and AOC India Participants , We will be tending to all queries in all the forums promptly as before, thank you for your understanding.

  1. Actuators' forces

    Hi Prakash, do you have any news about the problem? Best Regards
  2. Actuators' forces

    As you can see in the attachment, I've 36 excessive constraints... All the bodies can rotate around x-axis, but they can't translate along x, y, and z axis. I don't know how to solve this problem... best regards
  3. Actuators' forces

    i can give you the .mdl file, but to see the results you have to import the h3d file 13 times and divide every component (because I have 13 different components).
  4. Actuators' forces

    Hi Prakash, how can I check the joints and remove the redundant constraints? Anyway...actuators' forces may be around 100kN, but with this model (maybe because of redundancies) I obtained forces of about 300-400N, much lower from those expected.
  5. Actuators' forces

    Hi guys! I'm working with a cinematic model (how you can see in the attachments) and I'm interested to extract the actuators' force. Runned the analysis, MotionView showed me some warnings and I don't know if those warnings may compromise the analysis. Moreover I'd like to know if constraints are inserted correctly. I want to specify that when I ask the output (actuators' forces) to motion solve, I obtain some forces which aren't equivalent to those that they should really be. Thank you in advance, Best Regards.
  6. Constraint Reaction Query

    Hi, I tried using SPCFORCE, but in this way I got only the reactions of the ground constraints. I'm wanna obtain the reactions in some nodes with internal constraints; those nodes are not related with the ground. Thanks and best regards.
  7. Constraint Reaction Query

    Hi guys, I'm working with a fem model in Hypermesh and I need to extract the constraint reactions in some nodes. In particular way, these nodes, have no constraints with the ground, but they hinge two bodies between them through bars and rigids (as you can see from the attachments). Thank you in advance, Best Regards, Francesco
