    Hi Mohammad,

    If your simulation just has one channel, you can use the mapping opsion for mesh. If you have one cell or stack level simulation, you have two option. One is tetrahedral mesh. second one is dividing the curving place in geometry section as another domain. Using mapping for straight area, using tetrahedral for curving are.

    Best regards,

    Anil

    I agree with Anil.
    I would also recommed to do a mesh sensitivity analysis initially to find balance between mesh size and computation time. Also identify the areas you want to focus or expecting results for (like high stress etc.) and divide it into domains. So you can use finer mesh with higher order elements on the focus areas and coaser mesh on other areas. This will also reduce computation time. You can also use adaptive mesh feature if it is available in Ansys.

    I hope this gives you a direction to think!
