  Hi guys, I need some help analyzing simple crankshaft. I dont know which boundary conditions I have to set in a crankshaft. Please if you can help me. I am also attaching a picture. Thank you.

  Hi Ziga,
  Could you provide more information, such as the loads being used and the type of study you intend to conduct, so that it will be simple to provide the best kind of support or loading for simulation in Ansys?
  
  Thank you,

    Hi, I am working in static structural option. I need to define boundary conditions the same as in normal diesel engine.

  Hi Ziga,
  Apply a fixed support boundary condition to the main bearing journals of the crankshaft. This represents the rigid connection between the crankshaft and the engine block. If you want to consider frictional effects, you can apply friction coefficients to the contact surfaces between the crankshaft and other components, such as bearings and seals. This helps simulate the resistance and energy losses due to friction. It's important to note that the specific boundary conditions may vary depending on the type of analysis you are performing and the objectives of your study.
  Please check the below course for more details on structural boundary conditions.
