      Hello I have a strange problem while using Discovery, so please contact us. The current modeled part is 2mm thick. And Fidelity is 1.4mm at maximum. However, looking at the analysis results, it seems that the fluid does not recognize the wall and comes out. Please check whether this part is not recognized even though it is larger than the Fidelity value. thank you.

      Hello smjang

      Generally it is recommended to have at least 2x smaller element size than the smallest feature. This is due to the location of the cartesian grid. If you get exactly one cell across that thin element, then you are ok with 1.4mm. If not, then you cannot fit two of them, so it gets defeatured. Please can you try using a graphics card with more memory, see if that helps.

      Regards.

        Devendra Badgujar Thank you for answer. Up to this point, I thought that all the smallest Fidelity values were recognized. However, I found out this time that it is sometimes not recognized by the Cartesian grid. We will use it as a reference for using Discovery in the future. thank you.
