[ERROR] : (time step: 2) Particle 1 from element 1 lies outside the mesh. X, Y = Infinity NaN

When conducting the landslide analysis, I encountered the problem of Particle 1 from element 1 lies outside the mesh.But I can calculate normally without using the VG model.My steps and data settings are as follows:




seepage face

infiltration



calculate data

Have you considered extending the model so that the slope material points do not get too close to the boundary?

Hello, I haven't considered expansion yet. May I ask if it means adding a certain area to the edge of the model? My error message indicates that the position of the material point is "inf". Will this affect the effectiveness of the extended model?

[AgustinToroF]

If an error appears in Anura3D during the calculation phase, it's possible to visualize the results in Paraview before the error occurs, for example.

In the models I've created, I haven't considered the liquid retention curve (VG), but I have observed, as a warning, that some material points fall outside the limits of the numerical model. Extending the model helps avoid this problem, as does including a degree of damping.

Thank you for your suggestion.

Could you please provide me with some examples of the extended model so that I can have a reference? I'm not sure how to proceed. If possible, I would be very grateful. My email address is [email protected].

What is the final solution? I also encountered a similar problem:
[ERROR] : (time step: 1) Particle 1 from element 1 lies outside the mesh. X, Y = NaN NaN

In your case, probably you should check your parameters and boundary conditions, since the solver cannot calculate a position for you particle. Run the software in debug mode to get a little bit easier to find where this problem is comming from.
