+The problem definition is exactly the same as that of [Disc with hole]({{<ref "mechanics-linear-disc-with-hole.pandoc">}}). 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:
+
+```xml
+    <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](https://github.com/ufz/ogs/tree/master/Tests/Data/Mechanics/Linear/square_with_deactivated_hole.prj)
+* [3D](https://github.com/ufz/ogs/tree/master/Tests/Data/Mechanics/Linear/ElementDeactivation3D/element_deactivation_M_3D.prj)
