Hello. Once again, thanks for the provided help. I have reviewed your attachements and performed some modifications. However, I am not yet obtaining suitable results. The undertaken modifications are: I have added the following flag to the calmped beam and pushing object solvers: Apply Contact BCs =...

Hello. Firstly, thank you for your rapid response and the provided material. However, after extensively reviewing the attached links, I am still unable to understand how to model the interaction between the two objects. To perform the simulation, I have considered that the beam is made of iron, whil...

Hello. I am writing this entry to askif it is possible to perform a 2D simulation of the collision between two bodies (see the attached Figure). Figure.png The simulation involves two solid bodies: a clamped beam (solid 1) and a rigid quadrangular object (solid 2). Initially, the beam is undeformed,...

Thanks, I finally managed to find the solution. I changed the solver execution to "After Timestep" and it worked.

Hello, thank you for your response. The 'partitioning.2' and 'partitioning.24' folders represent two different trials. If I am conducting the simulation using 24 cores, and as a result, the 'partitioning.24' folder is created, what do I need to specify in the .sif file? Thanks.

Hello, Firstly, thank you for your response. I hadn't considered that cause. However, I am unsure how to specify to ElmerFEM the directory for the parallel mesh. Could you please provide instructions on how to do so? Additionally, I have attached the case.sif file and a screenshot of the case folder...

Hello, I'm simulating the transient flow over an airfoil by using ElmerGUI. One of the goals is to compute the velocity and pressure values and store them into a human-readable file (.vtu for example). To do so, I'm using the ResultsOutput solver. However, I'm getting the resuts written each time-st...

Hello, I'm performing a simulation of the flow passed an airfoil by using ElmerGUI. One of the objectives is to calculate the lift and drag forces. To do so, I'm using the "Calculate Loads" in the Navier-Stokes solver and summing them over the airfoil using the SaveScalars solver. The .sif...
