    1. COHi again ! It's been a long time since I posted the last message, but I've been really busy the end of last year... Unfortunately, I didn't manage to model friction without inertia.. If you have any idea, I would greatly appreciate your help.

    2. COThank's Marco, you're right, with this code, I was able to simulate my model, depending on what kind of source I use for it (currently I can feed the model with a displacement, but not with a force), and I think that it's the problem. I think my model should behave in a certain way as a diode : - if the applied force is less than the limit allowed, there is no relative displacement between the two flanges - when the applied force becomes greater than the limit, the force transmitted to the other flange equals this limit and there is a relative displacement between the flanges

    3. COHi Michael, Thanks a lot, actually you're right ! I was thinking in terms of converting a behaviour usually defined for stress to force, and I didn't manage to think this way, but yes, it's "only" Coulomb friction !! You're also right about your second point : I don't want inertia, and I didn't manage to get something working, even with `m=0` and `annotation (Evaluate=true)`.... I'll try to look at the code defining the `MassWithStopAndFriction` to see if I'm able to rewrite something similar but without inertia, and I'll let you know.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
