setting up my structure and my fluid solver, I am getting the following error:
Advancing in time ---[precice] Compute write mapping from mesh "Fluid_Nodes" to mesh "Structure_Nodes". ---[precice] ERROR: The interpolation matrix of the RBF mapping from mesh Fluid_Nodes to mesh Structure_Nodes is not invertable. This means that the mapping problem is not well-posed. Please check if your coupling meshes are correct. Maybe you need to fix axis-aligned mapping setups by marking perpendicular axes as dead?
To find the problem, I’ve set the mesh for both solvers to:
[[0. 0. 0.] [1. 1. 1.] [2. 2. 2.]]
Still I am getting the same error. I do not understand, why such an error can occur, when setting the both meshes to the same value.
