Yes the subroutines are called for each integration point and yes you have to pass for DLOAD the pressure previously read from somewhere (this is what I do).

Well, I think you are right. For static aeroelasticity (divergence for example) you could use DLOAD for pressure loads. But since I am doing dynamic aeroelasticity (flutter) I am not only interested in pressure loads but also in shear loads which are important too. DLOAD can only loadpressures...

Yes, I have the solution now. You need Abaqus 6.5 which has a new loading type: "SURFACE TRACTION" and an associated user subroutine UTRACLOAD. You will still not be able to load forces but you can derive traction pressures from them (ABAQUS 6.4 let's you specify only time-varying normal...

Hi. Yes DLOAD is perfect for pressure but I need to transfer local forces. The solution of random numbers... I don't think it's a solution. I calculate forces due to fluid motion (pressure forces and viscous forces) and I want to load them on the structure during a *dynamic, implicit analysis...

Hi, Is there a way to impose random time-varying concentrated loads on a structure? Something similar to DLOAD user-subroutine maybe? I want to load a structure with time-varying pressure forces and viscous forces. Thanks.
