Setting valve motion in tutorial port fuel injection

      I was training with Forte Academic version and scaled down inside Forte by 40% tutorial chapter 5 port fuel injection but valve error movement failed. Originally tutorial valve set up as shown below, was this angle setup main cause for error? i ttried picking coordinates on middle of valve face but no result.

      Accept the default Global Origin for the Reference Frame. Select Spherical for the Coord. System under Direction for the valve motion and set   =199 degrees and   =0.0 degrees.

      Hello,

      If the geometry is scaled/changed, you must check all the inputs that include numerical values as they will most likely need adjustments. For example, any local reference frame definitions, direction vectors, valve lift profiles, piston movement data, material point location, etc.

      Thanks for your repy Ren.

      I think it is to d with the theta=199' angle because the shrinkage would effect it but I didnt know how to alter the 199' accordngly.

      Stopped running because nothing happened, now unable to upload valve profiles. I t will be good if I can upload valve profiles from tutorial 5 or 8 (https://ansyshelp.ansys.com/public/account/secured?returnurl=/Views/Secured/corp/v242/en/forte_tut/chapter_h2_engine.html), but when I go for Create New, no menu appears for uploading.

      1. Theta = 199, this is 19 deg from the negative z-direction. I think can check/measure the angle in SpaceClaim.
      2. Create new profile, after selecting "Create New", click on the icon with a pencil to open up the editor. You can load a CSV file or copy paste from Excel.

      Restarted and got rid of errors hopefelly never see them again! Now I cant see the valve profile after scaling down the tutorial (Forte tutorial 5), cant upload valve profile using Create New. I got this selection menu but how can I get the valve profile shown in tutorial 5 entered here? I t would have been easier if Forte allowed for a sine wave option selected with max valve opening distance entered and thats sufficient for most cases.

      Another try again 47 minutes and stuck with this monitoring message, waiting for something to happen.
