Moving load analysis ABAQUS

[Sakthiiitm]

For the pressure moving load can we write subroutine in circular coordinate system? Because if I use Cartesian system i end up in very complex equations for pressure load for moving vehicle. Could anyone please tell me can we use circular coordinate system in *DLoad subroutine

 

[FEA way]

Subroutines use integration point coordinates (COORDS) so you would have to transform those. But unless your track is curved, it shouldn’t be necessary. You can find some examples of DLOAD subroutines used for moving loads on straight tracks even on YouTube.

If the bridge is curved bridge, then my vehicle will follow curved path. I cannot use normal cartersian coordinates, circular coordinates will make work easier as i want to represent a inclined trapezoidal area here.
