Hi

I am trying to model a finn with undulatory motion.

I am using the function to import smimport import the modeled fin with out the flexible mebran sheet in the midle from SolidWorks.

Then I have used the reduced order flexible block to model the flexible membran in the midle. I got following error

'Assem5']: The following errors were found in the model Assem5.

Caused by: ['Assem5']: Targets or motion inputs are specified for every joint around a kinematic loop: Revolute1 Revolute Targets for Revolute Joint 'Assem5/Revolute' are ignored. You can configure this diagnostic in the Simscape Multibody Configuration Parameters dialog.

My simscape model can be seen below

Hi,

I understand you are modeling a finn with undulatory motion and facing an error. The model throws that error because there are targets assigned to all the joints in the kinematic loop. To resolve the issue, you will have to remove the targets on that revolute joint or set the diagnostics for this condition in the Mechanics Explorer to "none".
