Attribute error

AttributeError: '<class 'phiml.math.magic.BoundDim'>' object has no attribute '_vertex_count'

Heya I tried running the new FVM_backstep examples.

I installed the latest phiflow and phiml packages.

Full traceback: { "name": "AttributeError", "message": "'<class 'phiml.math.magic.BoundDim'>' object has no attribute '_vertex_count'", "stack": "--------------------------------------------------------------------------- AttributeError Traceback (most recent call last) Cell In[4], line 3 1 boundary = {'x-': 1, 'x+': ZERO_GRADIENT, 'y': ZERO_GRADIENT, 'obstacle': ZERO_GRADIENT} 2 t0 = Field(mesh, tensor(0), boundary) ----> 3 t_trj = iterate(step, batch(time=100), t0, dt=.01, range=trange)

Running the FVM_Backstep and heat examples, once i get to math.iterate

Oh, that must have crept in with the latest merge. I'll look into it.

This is now fixed on the develop branch which you can get with

pip install --upgrade git+https://github.com/tum-pbs/PhiFlow@develop
