curve the mesh failed in PointWise for high order mesh

Studyhardhardhard

Hello, everyone.

If I import a geometric model first, divide the grid on the basis of it, and then export it as a high-order curved grid, the grid is curved smoothly.

Now, if I have a grid of CGNS and the geometric model matched with this grid, I use pointwise software to open the model and geometric file and export it as a high-order curved grid.

The grid is not curved, and the exported result is a high-order straight grid. Why?

In this case, how can I generate curved high-order curved grids?

Thank you for everyone!

Best Regards

    Hello again,

    On another thread, you asked the question below. As mentioned in that other thread, in order to keep things organized, I will reply to this question here. 

    "By the way, after the high order curved mesh is generated, the Jacobian message is printed.But when I open the generated high order curved mesh with Gmsh and compute it using Gmsh’s mesh quality module, I find that the difference between Gmsh's minJ/maxJ and the Pointwise's Scaled Jacobian are not equal, please forgive my ignorance, I always thought Scaled Jacobian= minJ/maxJ, where did I misunderstand? How can I find out how the Jacobian, Scaled Jacobian, Normalized Jacobian is calculated after the high order curved mesh is generated and printed? I want to compare it with Gmsh's."

    Unfortunately, I am not familiar with Gmsh and how it computes Jacobians. As for Fidelity Pointwise, please refer to this paper for additional details on this topic: https://arc.aiaa.org/doi/10.2514/6.2016-3178.

    I hope this helps!
