Linear; Element deactivation

• Mechanics/Linear/square_with_deactivated_hole.prj

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:

• 2D
• 3D
