+# Objective
+# =====================================================================================
+#
+# The Simulation focuses on simulating turbulent airflow through a cylindrical test chamber
+# containing a steel probe, and analyzing the deformation of the probe due to
+# aerodynamic forces. The deformation is assumed to be small enough that it
+# does not influence the fluid flow, allowing for a one-way coupling approach.
+
+#######################################################################################
+# Problem Description:
+# =====================================================================================
+#
+# The cylindrical test chamber is 20 cm long, with a diameter of 10 cm.
+# Turbulent air enters the chamber at 100 m/s, flows around and through
+# the steel probe, and exits through a pressure outlet.
