In order to get a realistic behaviour of a crane simulator I would need to set the "var CMF" value in "ph_setcorrections" to very small value.

Unfortunately there seems to be a limitation which doesn't allow values below 0.0005, which still is a to big for my application.

Is there a way to overcome this limitation?

and how ph_sercorrections will make realistic behavior for you crane?

For the setup of the crane we used naturalistic, means quite big dimensions and weights. In doing that the crane joints still behave quite "weak" when using the minimal possible value of "var CFM".

The only possible solution then is to set the mass of the crane parts and responding the joint forces to unrealistic low values. Unfortunately there are side effects like unrealistc movement of applied weights or unexpected behaviour of movements of the crane in certain positions.

what i can recommend for you, is to play with mass. And i think ph_setcorrection is not the way to solve this problem

Well, that was what I did.

Unfortunatly the behaviour of the crane parts became somehow unrealistic.
A bit like made out of paper ...

But obviously there is no other possibility.
