]]> Is it possible to linearize the model about a desired position? https://www.robotran.be/faq/is-it-possible-to-linearize-the-model-about-a-desired-position/ Sat, 21 Mar 2020 15:38:16 +0000 https://www.robotran.be/?post_type=faq&p=240 Yes, it is possible to linearize the model thanks to the MODAL module. The way it is generated depends on the chosen programming language. For more information, contact us.

Then, equilibrium and modal analyses […]

User models can be used as variables or parameters in your code. Note : if you want to integrate a time-variable value, an elegant way is to use the user derivative functionality (see “User […]

Can I easily rename it by windows interface? https://www.robotran.be/faq/how-can-i-rename-project-can-i-easily-rename-it-by-windows-interface/ Sat, 21 Mar 2020 15:45:35 +0000 https://www.robotran.be/?post_type=faq&p=246 There is no easy way to rename a project. If you want to rename it, change the name file of the .mbs file. In the .mbs file, modify the field “mbsname”. Then, delete the symbolic functions which contain the previous name of your project. Update the project name in the main function. Generate the new […]
