Execution Time Problem on 3D uniaxial compressive simulation #649 from Github

by Yang, Kedi

Hi guys, Currently, I am using Sfepy to simulate a 3D geometry model with a uniaxial displacement to find out the von Mises strength and the total execution time for the simulation is about *40 mins with 8G RAM*. Besides, 94% of the RAM is occupied when the program is running. I am not sure what is causing this execution time to take that long and what I could do to shorten the execution time. The geometry model was inputted from an Abaqus input-file with 5514 vertices and 4417 cells. Also, I have checked the execution time line-by-line and found that the most time consumable step is defined as: state = pb.solve(status=status) In this case, I am supposing the solving process used most of the RAM and causing the timing issue. The mesh file and our code is attached. Thank you and best regards! Kedi Yang

error of gen_yeoh_tl_up_interactive.py

by Takuo Fujita

Hi, Thank you for the release of 2020.3. I appreciate it. I tried the new example, gen_yeoh_tl_up_interactive.py. I encountered the error below. $python examples/large_deformation/gen_yeoh_tl_up_interactive.py Traceback (most recent call last): File "examples/large_deformation/gen_yeoh_tl_up_interactive.py", line 424, in <module> main(args) File "examples/large_deformation/gen_yeoh_tl_up_interactive.py", line 327, in main integral, omega, m1=m_1, v=v, u=u) File "/home/pyontaku14/anaconda3/lib/python3.7/site-packages/sfepy/terms/terms.py", line 342, in new raise ValueError(msg) ValueError: term 'dw_tl_he_genyeoh' is not in ['d_of_ns_min_grad', 'd_of_ns_surf_min_d_press', 'd_sd_convect', 'd_sd_diffusion', 'd_sd_div', 'd_sd_div_grad', 'd_sd_lin_elastic', 'd_sd_st_grad_div', 'd_sd_st_pspg_c', 'd_sd_st_pspg_p', 'd_sd_st_supg_c', 'd_sd_surface_integrate', 'd_sd_volume_dot', 'd_sum_vals', 'd_surface', 'd_surface_flux', 'd_surface_moment', 'd_tl_surface_flux', 'd_tl_volume_surface', 'd_volume', 'd_volume_surface', 'dw_adj_convect1', 'dw_adj_convect2', 'dw_adj_div_grad', 'dw_advect_div_free', 'dw_bc_newton', 'dw_biot', 'dw_biot_eth', 'dw_biot_th', 'dw_contact', 'dw_contact_plane', 'dw_contact_sphere', 'dw_convect', 'dw_convect_v_grad_s', 'dw_diffusion', 'dw_diffusion_coupling', 'dw_diffusion_r', 'dw_div', 'dw_div_grad', 'dw_elastic_wave', 'dw_elastic_wave_cauchy', 'dw_electric_source', 'dw_jump', 'dw_laplace', 'dw_lin_convect', 'dw_lin_convect2', 'dw_lin_elastic', 'dw_lin_elastic_eth', 'dw_lin_elastic_iso', 'dw_lin_elastic_th', 'dw_lin_prestress', 'dw_lin_strain_fib', 'dw_non_penetration', 'dw_non_penetration_p', 'dw_nonsym_elastic', 'dw_of_ns_surf_min_d_press_diff', 'dw_piezo_coupling', 'dw_point_load', 'dw_point_lspring', 'dw_s_dot_grad_i_s', 'dw_s_dot_mgrad_s', 'dw_shell10x', 'dw_st_adj1_supg_p', 'dw_st_adj2_supg_p', 'dw_st_adj_supg_c', 'dw_st_grad_div', 'dw_st_pspg_c', 'dw_st_pspg_p', 'dw_st_supg_c', 'dw_st_supg_p', 'dw_stokes', 'dw_stokes_wave', 'dw_stokes_wave_div', 'dw_surface_dot', 'dw_surface_flux', 'dw_surface_integrate', 'dw_surface_ltr', 'dw_surface_ndot', 'dw_tl_bulk_active', 'dw_tl_bulk_penalty', 'dw_tl_bulk_pressure', 'dw_tl_diffusion', 'dw_tl_fib_a', 'dw_tl_he_mooney_rivlin', 'dw_tl_he_neohook', 'dw_tl_membrane', 'dw_tl_surface_traction', 'dw_tl_volume', 'dw_ul_bulk_penalty', 'dw_ul_bulk_pressure', 'dw_ul_compressible', 'dw_ul_he_mooney_rivlin', 'dw_ul_he_neohook', 'dw_ul_volume', 'dw_v_dot_grad_s', 'dw_vm_dot_s', 'dw_volume_dot', 'dw_volume_dot_w_scalar_eth', 'dw_volume_dot_w_scalar_th', 'dw_volume_integrate', 'dw_volume_lvf', 'dw_zero', 'ev_biot_stress', 'ev_cauchy_strain', 'ev_cauchy_strain_s', 'ev_cauchy_stress', 'ev_cauchy_stress_eth', 'ev_cauchy_stress_th', 'ev_def_grad', 'ev_diffusion_velocity', 'ev_div', 'ev_grad', 'ev_piezo_strain', 'ev_piezo_stress', 'ev_surface_div', 'ev_surface_grad', 'ev_surface_integrate', 'ev_surface_integrate_mat', 'ev_volume_integrate', 'ev_volume_integrate_mat'] $ What should I do to solve the error? Should I edit terms.py? Best regards, Takuo
