Road PCD Marker Broken
Hello all,
I am trying to use a custom PCD road by following the various guides. But the .rdf file when importing into Motionview has this weird spike that seems to be where the road marker is.
Is there a way that I can fix this because the Hypermesh part looks normal, also the .fem file seems to look like others I have seen
see attatched files for .fem and .rdf if that is the problem
Hyper mesh is on the origin 0,0,0
This is for a university thesis so help would be much appreciated

Altair EmployeeHello @WillJones0701 ,
Going off of @Vishvam , another good source for generating the road surface can be found here:
It is used for soft soil road, but the process in HyperMesh is the same (just an extra rdf for MotionView). Make sure that the nodes/elements are renumbered starting from 0 and incrementing up by 1. In addition, it is preferred to have the surface aligned in the ZX plane.
Hope this helps.

It was the origin that was the problem in the end, that video helped.
A follow up if you could, now that its in there it doesn't go over the road just drives flat.
Even with the road course event switched to the .rdf file
i am using MF tire as per this tutorial and have made sure everything is the same
I downloaded the model for this and just replaced the road here with my road, and this also didn't work making sure that everything else was the same apart from the .rdf file in the event.
Any help on why would be much appreciated @Vishvam @Christopher_Fadanelli
Altair EmployeeHi @WillJones0701 ,
Can you try this for me. Incorporate the rdf in the AutoTires, then in the Road Course Event change the road type to Tires?
Could you also supply us with the updated .fem and rdf file?

Here is the updated .fem and .rdf
sorry not sure how to incorporate the rdf into the autotires, pretty new to all this
thanks
Altair EmployeeHi @WillJones0701 ,
Thank you for sending the updated files. I also observed the same behavior as you. My initial guess is that it still has to do with the setup of the elements in the .fem file. So in Hypermesh, I combined all the surfaces together and re meshed it with free tria elements (size 100).
I imported the road into MotionView and the vehicle traverses over it.
Attaching the updated files.
To have the AutoTire Entities reference the road. Go to AutoTires> Tires> select the tire, in the entity editor you can update the road profile.
For more reference I would suggest to go over our free eLearning's.

Hello @WillJones0701,
There are some best practices for creating a PCD road. I have attached a ppt showcasing it.
Although your .fem file looks fine, but the complete mesh doesn't seem to be connected when I select the elements using "attached" option. That means there are some gaps in between. Also try to make it a single component instead of multiple, tria mesh are always preferred.
See below attached image from your FEM file. The mesh needs to be continuous as shown in the ppt.
