Bolt Pretension#
This example demonstrates how to insert a Static Structural analysis into a new Mechanical session and execute a sequence of Python scripting commands that define and solve a bolt-pretension analysis. Scripts then evaluate the following results: deformation, equivalent stresses, contact, and bolt
Import necessary libraries#
import os
from ansys.mechanical.core import launch_mechanical
from ansys.mechanical.core.examples import download_file
from matplotlib import image as mpimg
from matplotlib import pyplot as plt
Launch mechanical#
Launch a new Mechanical session in batch, setting the cleanup_on_exit
argument to False. To close this Mechanical session when finished,
this example must call the mechanical.exit() method.
mechanical = launch_mechanical(batch=True, cleanup_on_exit=False)

Symmetric Deformable- deformable contact pair identified by real
constant set 23 and contact element type 22 has been set up. The
companion pair has real constant set ID 22. Both pairs should have
the same behavior.
MAPDL will keep the current pair and deactivate its companion pair,
resulting in asymmetric contact.
Contact algorithm: Augmented Lagrange method
Contact detection at: Gauss integration point
Contact stiffness factor FKN 1.0000

Max. initial friction coefficient MU 0.20000
Default tangent stiffness factor FKT 1.0000
*WARNING*: It is highly recommended to set KEYOPT(10)=0 (update contact
stiffness at each iteration) in order to achieve better convergence.
Use constant contact stiffness

in-core memory mode. This memory mode uses the most amount of memory
in order to avoid using the hard drive as much as possible, which most
often results in the fastest solution time. This mode is recommended
if enough physical memory is present to accommodate all of the solver
