How to import grid with results

Thank you for the Bempp discussion platform! I have encountered the following issues and would like to discuss them with everyone.

My question is Can Bempp import grids with result data?
I would like to skip the process of solving the BIE and directly import previous surface calculation results for far-field acoustic radiation computation and post-processing.
I have attempted the code below, but it appears to only import grids without result data.

phi_cal = bempp.api.import_grid(“result.msh”)

1.Save your result gridfunction and coefficients
bempp.api.export(‘sol.msh’, grid_function=sol)
np.savetxt(‘coefficients.csv’, sol.coefficients.reshape(-1, 1),
delimiter=‘,’, fmt=‘%f’)
2.Reimport and Build Gridfunction
grid = bempp_cl.api.import_grid(‘sol.msh’)
space = bempp_cl.api.function_space(grid, “DP”, 0)
data = np.loadtxt(‘coefficients.csv’, delimiter=‘,’)
sol = bempp_cl.api.GridFunction(space, coefficients=data)
