Insufficiently constrained structural model in Ansys

I want to analyze this model that is stressed and deformed. I fixed the lowest of points in the x, y, and z directions, and I pulled top of points upward (y direction). When I run the model in Ansys I got the following error: Check for…

ANSYS APDL Shape memory effect option of SMA not working

I am trying to define the material properties of a shape memory alloy material in ANSYS APDL V15. There are material properties for Superelastic materials (SUPE option) and material properties for Shape memory effect materials (MEFF option)…

How to design the most hydro/aerodynamic shape for a 'vehicle' that goes back and forth (using ANSYS)?

I am interested in making a very small scraper blade that moves back and forth along a submerged surface, however I need to make it as hydrodynamic as possible so I disturb the liquid as little as possible. I understand I can model different things…

Residuals of continuity not converging

I'm simulating a turbine. The convergence of solution is monitored by checking the residuals of the numerically solved governing equations. The "viscous-spalarat-almaras" model is used, and used air with constant density. Pressure-velocity coupled…

How to simulate a crack in a PCB?

I want to break this PCB with some know force of X newtons in the bottom left tip of the PCB. The problem is that in Static Dynamics I just get infinite deformation and in explicit dynamics I really don't know what to do. Anyone knows how to do…

Streamlines at the boundary of rotating and stationary domains are malformed

I am simulating a turbine and have divided the mesh into domains: the piping before and after the blade and the turbine blades. The domain containing the blades rotates at 2000 rpm while the other domains are stationary. The mesh is structure and…

ANSYS Workbench/Mechanical: Automatically export chart?

I'm running a simple tensile test simulation for a single element. Under Results I made a Chart object with Stress vs Strain, which can be manually exported to a csv file by right clicking on the table. The trouble arises from the parametrization.…

Explicit Dynamic ANSYS - Origami structure

I am working on a flat-foldable conical structure and I would like to carry out some dynamic tests on it (deployment to get the displacements and accelerations...). I have designed the folded geometry of this conical structure on Soliworks. This…

What is the script function to select Solid Body in ANSYS Design Modeler?

I need to select a solid body in ANSYS Design Modeler, with script, in a design with multiples bodies. With the following command I select all the solid bodies, but this is not what I need. ag.bodyPick; ag.gui.SelectAll(); I'm creating a script to…

How to compare two ANSYS mechanical APDL databases? (.db or .dbb files)

I am new to using ANSYS. I use the student version. Is there a way to find what is the difference between two .db or .dbb files? I have two files say a.db and b.db, which are supposed to be the same exact model for a simple beam structure with one…

Interference fit problem in ANSYS Workbench 16.1 - how do I get rid of pressure/displacement raisers?

I have an interference fit problem of two perfect cylinders modelled in 2D using symmetry. The overall interface pressure is around 20MPa lower than the hand calculations and I get non-uniform displacement / pressure near the edges of the model. Any…

How to represent a load supported at multiple points on multiple beams?

I have a frame, similar to a container frame, with two vessels inside. Each vessel is supported at four points on two beams, as shown in this mockup: I am using ANSYS to simulate the loaded frame. How should I represent the impact of the weight of…

Non-Linear Analysis Convergence Problem in Ansys

I am currently conducting a static structural analysis study in Ansys and encountered convergence prolems. I have a very large thermal gradient (almost 600°C) as input from a precedent transient thermal analysis which I apply gradually. I am looking…

Why should I use a contact between two glued bodies in FEA when I can directly merge the mesh nodes between them?

So I am using ANSYS to conduct a FEA analysis. I have two options to built a connection between two bodies; first is I can use a contact (like bonded) between the touching faces and the other option is I can simply merge the topologies of the two…

How to simulate the contact between two distant parts in Ansys workbench？

I made a test in Ansys but the result doesn't seem to be the final steady state. The two bodies didn't touch each other. How can I get the right result?
