Hi,
I want to impose boundary conditions based on our fluid dynamic simulations. The data is 3D + time and stored as tetrahedral meshes. I have been reading how to import the geometry from .stl files, but I’m not sure how to import the time-resolved velocity as boundary conditions. I have separated the inlet and outlet surfaces and extracted the velocity data as flattened numpy arrays. Then, I have been trying to load the velocity data through PointwiseBoundaryConstraint.from_numpy(), but I keep getting the following error:
File ~/modulus/examples/RT/code/temp.py:107 in <module>
inlet = PointwiseBoundaryConstraint.from_numpy(
File ~/miniconda3/envs/torch/lib/python3.8/site-packages/modulus-22.3-py3.8.egg/modulus/continuous/constraints/constraint.py:178 in from_numpy
return cls(dataset, nodes, num_workers, loss)
File ~/miniconda3/envs/torch/lib/python3.8/site-packages/modulus-22.3-py3.8.egg/modulus/continuous/constraints/constraint.py:257 in __init__
invar = geometry.sample_boundary(
AttributeError: 'list' object has no attribute 'sample_boundary'
I’m sure I’m missing something important. I have attached a sample inlet surface if it may be of help.
