AxisVM

An AxisVM binding has been developed by VIKTOR to simplify the process of creating and analyzing an AxisVM model. VIKTOR's AxisVM integration requires a specific AxisVM worker which can be downloaded here.

note

This binding was tested in AxisVM version 5. We cannot guarantee that the binding in combination with the worker will function properly with other versions of AxisVM.

Creating a Model

An AxisVM model is made by starting off with an empty model and creating/modifying objects via their respective interfaces. The following Model interfaces are available:

Below is an example of a model, representing a cantilever beam bending under its own weight:

from viktor.external.axisvm import Modelfrom viktor.external.axisvm import Materialmodel = Model()  # Initialize the empty model.material = model.materials.add_from_catalog('C12/15', Material.DesignCode.EURO_CODE)cross_section = model.cross_sections.create_rectangular(0.01, 0.01)n1 = model.nodes.create(0, 0, 0)n2 = model.nodes.create(1, 0, 0)beam = model.lines.create(n1, n2).define_as_beam(material, cross_section)model.node_supports.create_relative_to_member(n1, stiffness_x=1e10, stiffness_y=1e10, stiffness_z=1e10,                                              stiffness_xx=1e10, stiffness_yy=1e10, stiffness_zz=1e10)load_case = model.load_cases.create()model.loads.create_beam_self_weight(load_case, beam)model.results.nodal_displacements([n2])

Running an AxisVM analysis

The model can be fed to the AxisVMAnalysis as follows:

from viktor.external.axisvm import AxisVMAnalysis# Run the analysis and obtain the results, model (.axs) and/or result file (.axe).analysis = AxisVMAnalysis(model, return_results=True, return_model=True)analysis.execute(timeout=25)  # make a conservative estimation of the time needed to finishresults = analysis.get_results()  # obtain the results in a dictmodel_file = analysis.get_model_file()  # obtain the model file (.axs)result_file = analysis.get_result_file()  # obtain the result file (.axe)

If return_results is set to True, an analysis will be performed and the following methods become available:

If return_model=True, the model file will also become available:

caution

AxisVMAnalysis.execute needs to be mocked within the context of (automated) testing.
