Python Scripts For Abaqus Learn By Example Pdf ✨

def getFirstDialog(self): return BeamPlugin(self) toolset = getAFXApp().getAFXMainWindow().getPluginToolset() toolset.registerGuiMenuButton( buttonText='Parametric Beam', object=BeamForm(None), messageId=AFXMode.ID_ACTIVATE, icon=None, kernelInitString='execfile("beam_script.py")' )

# Submit job jobName = f'Job_Mesh_size' job = mdb.Job(name=jobName, model=modelName) job.submit() job.waitForCompletion()

# Get last step, last frame step = odb.steps.values()[-1] frame = step.frames[-1] # Reaction force (RF) rf_field = frame.fieldOutputs['RF'] total_RF = sum([value.data[1] for value in rf_field.values]) # Y-direction sum output_lines.append(f"filename, Total RF = total_RF:.2f") odb.close() with open('reaction_forces.csv', 'w') as f: f.write("ODB_File, Total_RF_Y\n") f.write("\n".join(output_lines))

Save as cantilever_beam.py and run from Abaqus command line. 4. Example 2: Material Parameter Sweep (Loop Over Young’s Modulus) Goal: Run multiple analyses with varying material stiffness and collect max displacement. python scripts for abaqus learn by example pdf

# Clean up del mdb.models[modelName] output_file.close() print("Parameter sweep complete. Check sweep_results.txt")

for E in modulus_values: modelName = f'Model_E_int(E)' mdb.Model(name=modelName) # ... (beam creation similar to Example 1, but with E variable) # Omitted for brevity – reuse Example 1 with dynamic model naming

# batch_postprocess.py import os from odbAccess import * odb_folder = './simulation_results/' output_lines = [] # Clean up del mdb

# Extract max displacement from .odb odb = openOdb(path=jobName + '.odb') lastFrame = odb.steps['ApplyLoad'].frames[-1] displacement = lastFrame.fieldOutputs['U'] max_disp = max([value.dataDouble for value in displacement.values]) output_file.write(f'E, max_disp\n') odb.close()

print("Batch post-processing done.") Goal: Build a simple dialog to input beam length and force.

# beam_plugin.py from abaqusConstants import * from abaqusGui import * import os class BeamPlugin(AFXDataDialog): def (self, form): AFXDataDialog. init (self, form, 'Parametric Beam', BUTTON_OK | BUTTON_CANCEL) AFXTextField(self, 8, 'Length (mm)', form.lengthKw) AFXTextField(self, 8, 'Force (N)', form.forceKw) # beam_plugin

Scripting enables automated parametric studies without manual GUI interaction. 5. Example 3: Automating Mesh Convergence Study Goal: Refine mesh iteratively and track stress at a critical point.

# parameter_sweep.py from abaqus import * from abaqusConstants import * from caeModules import * import os modulus_values = [1e5, 2e5, 3e5, 4e5] output_file = open('sweep_results.txt', 'w') output_file.write('YoungsModulus, MaxDisplacement\n')
