Re: Damping in ANSYS
The Newmark and HHT methods have some numerical damping. Review the settings on the TINTP command.

Re: Safety Factor calculation
Hi @skadam ,
One may refer the following link on using Stress Tool which has further links on calculating safety factors for different stress results: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v191/wb_sim/ds_Stress_Tool_o_r.html?q=stress%20safety%20tool

Re: Current Excitation in Maxwell
Hi,
Since the coil model is solid and a section is used to create the current excitation terminal. You need to provide "Number of turns*Current " as the value for current excitation.

Re: I can't get the Monte Carlo Ray Tracing Model to run on my Fluent simulation
Use a solid: it just says it doesn't like thin walls.

Re: Need help meshing this problematic geometry
From internal side you have sharp angles. Please remove those sharp angles as shown below. Then use meshing.
Also please select physics preference as CFD in meshing. Please use proximity sizing to capture gaps between faces.
Please see help manual for more details about these commands.

Re: How do I mesh this tube/body properly?
Hi @Flatter97xD What do you mean by mesh wont fit?
If you are using a newer version(2019R2 or newer), you can use "Axisymmetric sweep" for a body of revolution to create hex/prism meshes
If you need a connected mesh, then you can use shared topology in geometry editor(DM or Spaceclaim). If you use shared topology, axisymmetric sweep will not work.

Re: SolidWorks Monte Carlo Ray Tracing Settings
Hello,
Here is one example of Monte Carlo Radiation modeling in Fluent. Please watch this Ansys How To video to understand the set-up better.
There should be other YouTube videos similar to this, which can help you get started.
There is also a tutorial in our Fluent Product Documentation. Here is the link. Please see if this helps.
Thank you.

Re: Penalty factor in topology optimization
Hi @skadam ,
Penalty factor is used to scale the structural stiffness matrix of each element depending on the topology density (which is calculated during solution as between 0 and 1). The higher the Penalty Factor, the more the stiffness matrix is weighted towards elements with a density close to 1 - i.e. less ambiguity in portions to keep/discard. This factor is penalizing the stiffness matrix with this equation penalized stiffness = ( pseudo density)^penalty factor × stiffness. The higher the penalty factor, it reduces the grey region in the final design. The less the grey region, the better is the design. So the users once have selected the design can deploy this to reduce the grey regions in the design. The penalty factor cannot be very high value because it creates a huge gradient between different elements and make the solution unstable. The stiffness will not be high because the pseudo density is always between 0 and 1. But it creates a huge gradient of how stiffness is varying in the design.
