Hello, I downloaded the installation file, and then attempted to check it in the cmd window as the instructions suggest. However, I do not get any result While installing it says: "Warning! PATH too long installer unable to modify PATH!" I also did not see an x64 version to try. I am wondering if it...

Re: Static Opt - DLASD4 paramater number -1 had an illegal v

Hello, I have tried to retry my analysis with OpenSim 3.3 however I still get the error: "** On entry to DLASCL parameter number 4 had an illegal value " When running through cmd. When I run the same analysis in the GUI the program crashes and closes. Any advice would be a huge help. Thanks, Alex

Re: Static Opt - DLASD4 paramater number -1 had an illegal v

Thanks for all the help! I have come across a similar error that also forces Static Optimization to quit. I was unable to find any mention of it on the forum. The error is: "** On entry to DLASCL parameter number 4 had an illegal value" Before it exits, it mentions that a muscle reaches its minimum ...

Re: Contact Forces not displaying

Hi, Thanks again for the quick response. I have read over this paper, but perhaps what I am missing or misunderstanding form it is: if I am trying to set EFM properties, do I need to adjust the Stribeck friction curve (Figure 5) with the appropriate static, dynamic and viscous friction values? Simil...

Re: Contact Forces not displaying

Hi James, Would you be able to explain a bit about how friction and dissipation are derived? I was not able to find a clear descriptor. Are these values normalized? I am finding that I need a very high dissipation value to get the desired penetration. Any comments would be a big help. Thanks. Alex

Re: Static Opt - DLASD4 paramater number -1 had an illegal v

Hello,

I have just come across this error on 3.2 (64 bit), so I reinstalled suggested, however I am still getting the error when running static optimization.

Where would we be able to get the "hand patching instructions"

Any help on this error would be really appreciated!

Thanks,

Alex

Accelerometer data as input to segment motion

Hello, I am looking into using tri-axial accelerometer data as input to the motion of a segment in my model. I expect there to be some higher frequency vibration that I would like to capture to some degree. I am hesitant to integrate, since I am not sure how well the vibration will be reflected in t...
