Physics Set-Up

Specify Material

Press Physics Region under Physics Definition, AIM should detect the body and highlight it. Now that we have the physics region defined, press next step and a dropdown menu should appear. Since the objective is now to select a material press Add > Physics Modeling > Material Assignment > Structural Steel. The entire object is now made of structural steel and we can , which is the default material in AIM.  We can immediately add our other constraints.

Boundary Conditions / Forces

Select the Physics task in the workflow. The first conditions that needs need to be specified for a structural simulation are supports, in . In this case, the supports will exist on the symmetry planes where we “cut” the model into quarters. Next to Structural Conditions press Add > Support then , select one of the cut sides as the location, and change the Type will be to User Specified specified. Edit the Translation drop down menus until there is only one arrow going into our model and , then repeat for the other side and the large quarter circle at one end. This creates a symmetrical constraint support for the shaft, which allows it to deform while also not translating or rotation rotating from its location.

Next, the pressure is added to the outermost face of the shaft by selecting the pressure Pressure option in the add Add drop down menu. It was given to us as 1000 Psi, but since AIM defaults pressures as compressive therefore , the correct value to input is -1000 Psi.
