Linear; Element deactivation

Project file on GitLab

The problem definition is exactly the same as that of Disc with hole. With the element deactivation approach, the problem is solved as 2D and 3D benchmarks, respectively.

The input data set of the element deactivation approach is specified inside the tag of <process_variable> ... </process_variable>. For example, the following input means to deactivate the elements with MaterialIDs of 0 within a time interval from 0 to 1:

    <process_variables>
        <process_variable>
            ...
            <deactivated_subdomains>
                <deactivated_subdomain>
                    <time_interval>
                        <start>0</start>
                        <end>1</end>
                    </time_interval>
                    <material_ids>0</material_ids>
                </deactivated_subdomain>
            </deactivated_subdomains>
            ....
        <process_variables>
    <process_variable>

The input syntax can be also found in the project files of the two benchmarks:
