STEP converted from STL

      Hi All,


       


      I am working on a Gyroid model. As I have to do analysis on Gyroid model I generate the Creo models of Gyroid and converted them into an STL. Next, I open STL into spaceclaim and convert it into solid and export them into STEP. now when I import them into ANSYS ( SEE attached screenshot) it shows as a facets. Now, I am struggling with apply boundary conditions. As I unable to select single surface.


       


      Kindly guide me with this.


      Thanks in advance


      Regards,

      Hi Pranav,


      From Creo, export a STEP file and import that into ANSYS SpaceClaim.  Don't use STL.

      P.S. Insert images directly into your Post because ANSYS staff are not permitted to open attachments.

      Hi Peter,


       


      Thanks for quick response.


      However, I already tried your mentioned step i.e. convert .prt file into STEP, but It didnt work. As the size of STEP file is only 3KB, and when I tried to open in spaceclaim the message pop-up as invalid geometry.


       


      Thanks,

      So that is a failure of Creo to export the STEP file.


      As I look at the image, there seems to be a periodic pattern of 5 units along each Cartesian direction. What happens if you take a single unit, so the geometry is 1/125 the size. Can Creo export just one unit?


      Another idea is to create this geometry in SpaceClaim instead of Creo.

      Hi peter,


       


      Apologize for very late response.


       


      Thanks for your help I created geometry into space-claim and than generate STEP through it and it worked in ANSYS.


      Regards,


      Pranav
