icepak (transient) time dependent movement?

      hi, does icepak (transient solution) have time-dependent movement option? whenever I use pwl(ds1, Time) for move parametric, icepak gives me "intrinsic error".

      then I added a new parameter like "SimTime" and changed the move parametric with pwl(ds1, SimTime).  This way not getting any error but it's not working like I want.

      I shared my project link below

      Dear Cagdas,  Thanks for asking question in learning forum. It would be better to create a support case so we can review your requirement.  Do you have access for support? Please create a case and attach the project file in support portal. Please let us know any comments.

       

      Regards,

        unfortunately no. I have no access support.

      Hi Cagdas, can you explain what do you mean by movement? Are you trying to do rigid body motion? Icepak only supports Wall Speed. Thanks.

        hi. I want to see how much a metallic material temperature changes in a long coil series from the beginning to the end. I can give motion to a material with an icepack parametric setup, but I cannot express this motion with time. For example, if the object has heated a certain amount at the beginning of the coil channel in 100 ms, it has also heated that much at the end of the channel. If I could adjust the change in position over time, I could observe how much it has heated along the channel. In maxwell I can do that with motion set up and band. Does icepak have any setup like that?

          Hi Cagdas, sorry that I am still confused. Can you clarify what do you mean by motion? Is the metallic material fluid? Are you trying to apply varing velocity to it? Thanks.

          it's a coil gun design. I want to see the temperature change along the barrel of an electromagnetic launcher consisting of 18 coils by applying current at three-phase different frequency values to the coils. thanks.

          Hi Cagdas, rigid body motion is not supported in Icepak. You will need to use Fluent for that. However, please consider whether the alternative is reasonable. Using only one coil in the model and divide the coild or the metallic material into certain sections based on the accuray you desire. Then for each section, change the power over time coresponding to the actual experimental setup. For example, the front end of the metallic material should be heated first at the begining of the simulation and the heating should stop after the front end leaving the first coil and then be heated again when this section enters the second coild. If you know the exact motion of the metallic material, you should be able specify the power over time accordingly on each section of the metallic material. Please let me know your thought on this. Thanks.
