Multi-threaded modeling in Robot

[Anonymous]

I know there is a wishlist for Robot, but this is not a wishlist as such, more general questions about the software;

1. Today, Robot has a multi-threaded solver, but everything else runs only on one thread, making wiriting of results or navigating and modelling big models very slow compared to other software. 

Is there any plan or progress on making the program run faster in this aspect where it actually utilizes the computational capacity the user posesses?

2. The non-linear solver cannon handle cable elements that does not have tension (slack cables), making common structures as cable-trusses and cable-roofs impossible in Robot. This should be a fairly easy numerical fix. Is there any information about future plans for this?

We know about bottlenecks resulting from not utilizing multithreading and full recources of the processor during pre- and post-processing.

Unfortunately I am not entitled to speak about any future development plans on the forum.

Can you give more details or some model which led you to such conclusions?

Generally modeling cables with low or no tension is no problem in Robot:

1/ if any load parpendicular to the cable is applied (selfweight is enough) that the cable is calculated as a cable and there will be always some non-zero tension force in it. Of course depending on working conditions of the structure it may by so that some cables will not be working but even in such case some small tension will be observed in them (resulting from for instance the self-weight of the cable)

2/ if there is no perpendicular load applied to specific cable then such cable is calculated as tension-only truss bar and depending on working conditions of the structure the precisely zero tension force can be observed in it.
