SubscriberHello,
I am having issues with meshing during pre-processing my UAV's fuselage model for a crash simulation. Let's start from the begining... I have .stl files of parts for a winged UAV, in order to perform the simulation the mesh is needed to be reduced which is why I am using Meshmixer and Fusion 360 to export the model as a body in .IGES file type. The following steps gave me error: "One or more entities failed to mesh. The mesh of the bodies containing these entities may not be up-to-date. However, meshing might be successful on the other entities."
Step 1: Importing the.stl and setting the reduce mesh
STEP 2: Import the reduced mesh to Fusion 360 and Convert mesh to body (Parametric - Faceted option)
STEP 3: Export the model to .iges
STEP 4: Import the model in Ansys Discovery and connect the Geometry block to the Explycit Dynamics block
STEP 5: Create Mesh
My question would be, what could I do to actually mesh the specified part model. Thank you in advance

Forum ModeratorYou may want to cleanup the iges in the Discovery and see if that helps?

SubscriberIn Discovery in the Repair tab I used the Check Gometry to see possible errors and this came up:
The repair all option just creates this icon and does not help:
Do i have to try and fix all of these errors manually or is there a better option? Secondly, if I did do it manually what tools should I use?
Thanks again
