Scan-and-Solve for Rhino

Simulate Early, Simulate Often... In Rhino

Hi all,

Another test with SnS has done,this time model changed ,not very big,but little complicated.

When solving the linear system,the progress bar goes back and forth,the same picture appears for nearly half an hour.Pls see the attachment.


I didn't know what‘s going on at first. So i terminated,and save the model to my workstation, a win7 64bit platform of course. I do know SnS havn't  64bit release,but more memory may make some doubts clear.

But it does't  buy my attempt.Pls see the attachment,
So i leave it. When i came back, the solution has finished,even i don't know when did it happened,how much time did this case cost?

If you know pls tell me.

S&S relies on an iterative linear solver, and its solution time depends on the quality (condition) of the linear system. The condition of linear system depends on the geometry, e.g. size of small features, and resolution. The progress bar measures the progress of the solution at every iteration, and it is normal to see the progress bar go back and forth -- as long as it progresses eventually to the solution. The iterative solver can fail in principle, but this happens very rarely, and in fact we do not have any such failed examples as of now.
Thank you,Vadim.
I get it.
But may i konw how much time did this solution-progress spent?

The model is look like as below,


Not very big ah~.
Good point. We will add the solution time to the report -- in the future versions of Scan&Solve.
Thank you for point this out.
Thank you, may ask for more. Not only the report, but also at the beginning after kicked the 'GO!'.
Time estimated is helpful to make a decision for coffee time. :)~
We actually thought about this. Unfortunately, the solution time varies greatly with the complexity of the geometry and boundary conditions and it is impossible to predict a priori. However, the solution *usually* scales linearly with resolution. So you can safely estimate the coffee time (or dinner time for some problems!) after you perform your first analysis on this problem.
