Failed to load library 'mblibv1'

I am trying to run the following simulink model which was developed using SimMechanics (v2.7) available at this link (Download the 2010 model (available for Academic or Non-Profit Organization Noncommercial research use only).

I tried to run the model in MATLAB 2020a and installed Simscape Multibody (v7.1), however, I am getting the following error: Failed to load library 'mblibv1'. How can this problem be resolved? Body sensors/body actuators are not recognized in the model.

Hi,

2019b Warns that " Simscape Multibody First Generation libraries will be deprecated. Use Second Generation Library (sm_lib)"

It’s because Simscape Multibody no longer supports use of first-generation functions and blocks in 2020a, so it cannot find the library mblibv1 .

As a workaround, you can do any of the following

• Run files in 2019b or earlier versions
• Update the model using blocks from Simscape Multibody Second Generation Library (sm_lib).
• Use Simscape Multibody 1G Conversion Assistant tool to build Simscape Multibody 2G model that provides same behavior as 1G model.
