Using SimScape Multibody in Matlab-online
显示 更早的评论
Dear all;
I am trying to build the simple pendulum model in SimScape Multibody using the Matlab-online version. However, I can´t configure the parameters of the different blocks. So far I tried the "Brick Solid" block and the "Rigid Transform" block. When I double-click the blocks there are either no parameters o they are greyed out. In the documentation, It is mencioned that "Multibody" is available in Matlab-Online but "Block parameters must be changed using the Property Inspector". So I tried to use the Property Inspector but is simply opens the block parameter diagram as it does with the "double click". Anyone can help me with this? What am I doing wrong?
Thanks
Thomas

The limitation on Simscape Multibody regarding block parameters was incorrectly stated on the Simulink OnlineSpecifications and Limitations page. Right now Simscape Multibody block parameters can only be viewed and changed via the API commands get_param and set_param in Simulink Online. For example, select the Revolute Joint in the double pendulum example and enter the following code to find all the block parameters and then view the damping coefficient value:
get_param(gcb,"ObjectParameters")
get_param(gcb,"DampingCoefficient")
If you want to change the damping coefficient, set the value as follows (note that the value must be entered as a string):
set_param(gcb,"DampingCoefficient","0.5")
We are working on addressing this limitation for a future version of Simulink Online.
