Hi, SnSScript is working fine for the last 3 weeks. With Rhino5 64Bit there are no memory or stability problems. The simulation has implied about 20000 invocations of the SnS so far. I think this is…Continue

Hi,are the results for the two attached files consistent (in the zip-files )? The two bodies are not very different, but the displacement is very different. Is this possible ?Best regardsiskContinue

Hi, SnSScript is working fine for the last 3 weeks. With Rhino5 64Bit there are no memory or stability problems. The simulation has implied about 20000 invocations of the SnS so far. I think this is a good product and suits well for the application as addin in Rhino.I would like to have some more information about the underlying algorithm: Are there any references to the convergence behavior of this method? I am interested in error bounds for the displacement. Thank you in advanceiskSee More

A value of -1.7e+308 is a generic invalid value indicating something is wrong in the querying process. If you turn on output with SetOutputOnOff, SnSScript will report to the command line information on the offending…"

"Hi Michael,
the plug-in works fine for me. The memory load is now ok. Also, the probability to interrupt the script with the keyboard has increased.
Another question: Can the function QuerySolutionValue(GUID, Component,…"

"Iván,
I've just uploaded the latest WIP of the SnSScript plug-in (Version 2012.7.8.0). One of the notable changes is that it no longer copies the geometry to the undo stack when changes are made to the Scan&Solve data.
Try…"

"Hello isk,
It appears you may have an error in your script in the following location:
P = Array(base_point(1), base_point(2), 0) FSu = SnSP.GetNearestFace(GUID, P)
In this code you are creating the point P using the 1st and 2nd entries in…"

Notwithstanding potential memory leaks in SnSScript, one thing that will help is to add the following in the loop in your script:

Memory problems
Hi everyone, The scripting engine for Rhino works great. I am running an optimization using Rhino 4 on Windows 7 (64 Bit). The goal function is a computation done with calculations from the SnS Scripting. The problem is: I don't know how to release the memory used by the plugin. Thus, after anumber of computations Rhino runs out of memory. I have attached the script file (e1.rvb)which illustrates the problem. So far the only workaround I have found, is to call the new command after a number…See More
