IK and grf

Hi,

has the ability to visualize the grf with the IK been disabled? i.e using a coordinate data file containing the grf's. Had no problem with 2.2.0, I'm aware that you can sync the motions but this was a useful tool.

IK computation time

Hi,

when running the IK tool with the plug in gait model (t=5secs) the computation speed is very slow, probably 1 frame per second. Is there an easy way to reduce this speed? any tips?

RE: missing example file

Hi Ayman,

I'm using version 2.2.1. It is possible that I inadvertently deleted that file. When I reinstalled all the files to run the ID were accounted for so it was probably my doing.

missing example file

Hi,

Not sure if i is just my copy, but the folder containing the Gait2354_Simbody example is missing the file subject01_walk1_grf.xml which is the external loads force set file. Any way of providing this files for the selections to create it?

Thanks,

IK - 'Coordinate data for trial'

<t>Hi,<br/> <br/> I've been looking at the Gait2354_Simbody example specifically the IK. I would like to know how the coordinate file (containing grf's only, all other columns = 0) was created as the number of frames in this file is less than the number of frames for the force file. Is there a stand...

Spine Model

<t>Hi,<br/> <br/> I'm after a full body model that has a more detailed description of the lumbar spine as I want to estimate joint loadings in this region during Sit-to-Stand. From what I've been told, most of the full body models approximate the lumbar joint as a simple ball and socket. I've seen t...
