We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi,

Yes, the geometry can be modified within the Forte UI to a certain extent using "Transform Mesh". For example, the piston and liner surfaces are scaled along the x and y directions by a factor of 1.2. If you try a much larger value, for example, 1.5, you'll see that some of the triangles on the symmetry plane start to become inverted because of excessive stretching. If a much larger bore is needed, you can first scale the whole geometry along desired direction(s) and then scale the "liner" and "piston" surface. To adjust the CR after the adjustment to bore and stroke, the Piston surface can be moved up or down to increase/reduce the CR. The CR can be checked using the CR utility on the menu bar.
