DO i have to use different engines CAD models for that or I can simply adjust that on the software. @raul.raghav @Kremella @abenhadj @rwoolhou @V. V.

Hi Favour:
Below are the answers to your questions:
1) The only limitation listed for the student version of Forte is the mesh size, which is limited to 1 million for fluids products. Here is an informational link to the student offering:https://www.ansys.com/academic/students/ansys-student2) I am still looking into the answer for this question. Normally the fuel can be modified to include various components, but this is done to create a surrogate blend that simulates the fuel in the reaction mechanism. It may therefore be necessary to create a different mechanism for each composition.3) The compression ratio can be adjusted in different ways without requiring new CAD geometry, depending on what really happens in the engine hardware. Here are a few typical scenarios:1) Adjust the stroke value on the piston boundary condition panel;2) Adjust the squish height by moving the piston in the imported surface mesh;3) If the engine contains a volume representing the crevice region, adjust the height of the crevice region.The “Compression Ratio Calculator” described in section 2.8.15 of Forte User’s Guide can be used to check the CR value during the setup stage.Best Regards,Judy
