Describe the issue

I am trying to get wall velocity gradients for my aneurysm problem. However, it doesn’t seem to work. modsim_var = csv_to_dict(to_absolute_path("modsim/modsim_wfenz_hiresbl.csv"), mapping) modsim_invar = {key: value for key, value in modsim_var.items() if key in ["x", "y", "z"]} modsim_invar_grid = normalize_invar(modsim_invar, center1, scale, dims=3) modsim_outvar = {key: value for key, value in modsim_var.items() if key in ["u", "v'', "w", "p",''u__y']} modsim_validator = PointwiseValidator(nodes=nodes,invar=modsim_invar_grid, true_outvar=modsim_outvar, batch_size=4096, plotter=ValidatorPlotter()) domain.add_validator(modsim_validator, "modsim_hiresbl_validator")
