Is there a faster way to restore the model's state to the end of the last step when conducting transient analysis? I have use the "database, save and restore" to save the model's state in files. However, the speed of "save/restore" is too slow. I wonder if there is a faster way. ...

If using recorders, I will have to parse the file to get data, which will make the program more trivial. I wonder whether there is a method/command to get the running state of the "analyze", i.e. running, stopped .... If the real time running state of the "analyze" can be obtaine...

Here is a simple code of the question. ... analyze 1 0.01; puts [nodeDisp 5 1] Do I need to check whether the analyze has been completed before the nodeDisp and nodeReaction are used? That's to say, if "analyze" and "nodeDisp" are asynchronous and the "analyze" is not c...

How to add a new time integration algorithm?
This link (http://opensees.berkeley.edu/wiki/index ... Integrator) is empty.
Thank you.

I wonder if I can set all the parameters in the C++ source code and run the analysis without tcl scripts.
It will be very helpful and make the program more flexible.
Are there any examples?

Thanks a lot.

I found that the "nodeReaction" command can output the node reaction.
But why wasn't it listed on the opensees command manual?

How to get real time node reaction?
Is there a command like nodeDisp?
Thank you.

Is it possible to output a model's global matrix (M, C, K, Q) with Tcl at a certain time step during a transient analysis?
How to do it?
Should I change the OpenSees code?
Thank you.
