PyDPF modules are also used for post-processing. The following topics are available: * `20.1. Introduction`_ * `20.2. Modeling`_ * `20.3. Modal analysis`_ * `20.4. PSD analysis`_ * `20.5. Exit MAPDL`_ * `20.6. Input files`_ This example is inspired from the model and analysis defined in Chapter 20 of the Mechanical APDL Technology Showcase Manual. 20.1. Introduction ------------------ 20.1.1. Additional Packages Used ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * `Matplotlib `_ is used for plotting purposes. .. GENERATED FROM PYTHON SOURCE LINES 20-33 20.1.2. Setting up model ~~~~~~~~~~~~~~~~~~~~~~~~ The original FE model is given in the Ansys Mechanical APDL Technology Showcase Manual. The ``pcb_mesh_file.cdb`` contains a FE model of a single circuit board. The model is meshed with SOLID186, SHELL181 and BEAM188 elements. All components of the PCB model is assigned with linear elastic isotropic materials. Bonded and flexible surface-to-surface contact pairs are used to define the contact between the IC packages and the circuit board. 20.1.3.

Modal analysis -------------------- 20.3.1. Run modal analysis ~~~~~~~~~~~~~~~~~~~~~~~~~~ A modal analysis is run using Block Lanczos.
