    btw, it's not the space.

    it also crashes v3.8.0 on linux.

    uh, this is the same request as "Add a ruler tool to calculate distances between 2 points on surfaces in the 3D geometry view".

    to avoid the discontinuity issue, you have to solve the extrapolation to the nodes globally, not just element by element.

    it is probably most accurate for you to map stress/strain values to the nodes by using the solver which gave you the integration point values you are trying to interpolate in the first place. this is because the proper interpolation depends on the basis functions you are using in your computations, which is not something paraview knows about.

    this is the relevant equation one needs to solve for this problem:
    <basis functions>*<unknown nodal coefficients>
    = <continuous function whose values are known at gauss points>

    the nice thing is that the newton-raphson scheme for computing this uses a constant mass matrix! thus the matrix can be precomputed, and solving the linear system is very fast and takes about one iteration.

    i hope this helps you (or future readers) with your simulations. i felt the same way you did until i sat down and worked out a generic "nodal interpolation" code. it's really not as hard as it seems at first, and it can be reused to interpolate any calculated value.

    We are working on this feature as well as the ability to linking the ParaView engine with the simulation (aka co-processing or in-situ processing)

    i think this has actually been done, and should make its way into a release sooner or later.
