1Get to know your tools

In this module, you will learn HyperMesh GUI, What is TCL compiler and hands-on practice of the TCL commands in Notepad++

  • HyperMesh GUI overview
  • TCL compilers
  • Notepad ++
  • “Hello World” TCL code

2Let’s learn a new language

In this module, you will learn TCL commands like loops, arrays and how TCL is linked with HyperMesh 

  • Looping structures
  • Array manipulation
  • TCL wiki
  • HyperMesh and TCL linkage

3Dissecting HyperMesh using TCL commands

In this module, you will learn several commands and how they can be used in HyperMesh to perform operations

  •  “ * ” and “hm_” commands

4Let’s build the GUIs with TK

In this module, you will learn how to build a GUI using Tk for the TCL command used in HyperMesh 

  • Introduction to TK
  • creating TK popup box
  • creating TK buttons
  • creating TK input boxes

5Problem of normal

In this module, you will be able to understand the problem of normals in pre-processing and how it will affect the results in a simulation. You will also learn how to automate to align the normal in a few quick mouse clicks.

  • Element normals and their  significance
  • Fixing normals: code vs. standard

6Let’s take care of “zero”

In this module, you will learn how to handle a null case when you write a code in HyperMesh to automate a process 

  • Handling null cases
  • Delete displayed
  • Delete empty
  • Isolate displayed

7Let’s meet the CAE nightmare – Free edges

In this module, you can understand the concept of free edges and how it will affect the simulation, and also you will be able to write a code to automate the fix for the Free edge issue that occurs during meshing.

  • Free edge and their significance
  • Detecting free edges using available tools


In this module, you will learn the significance of a collector, property card, and material card along with a manual method to assign them. Once you understand that you will also be writing code to automate the process.

  • Different collectors and prop and material assignment
  • Renaming- as per thickness

9Auto reflect

In this module, you learn the importance of Reflect command for the symmetrical models along with the manual renaming of the components and their material and property cards. Once you understand that this method is time consuming and tiring, you will also learn how this can be automated with a few lines of codes. 

  • Explain the physics
  • Explain procedure
  • CAD manipulation using TCL

10The importance of order

In this module, you will understand the significance of numbering  in a model for nodes, elements, components, sets, etc., and learn how to automate them with learn the code and its logic

Creating ordered sets

  • “Remembering” the selection order
  • Midline generation

11Element Quality Check

In this module, you understand the importance of mesh quality. You also understand the importance of automating this process

  • Quality criteria check
  • How to highlight these elements
  • Popup and report generation


In this module, you will learn how to code to automate the part list and how to read and understand the Userpage.mac

  • Auto part list
  • Userpage.mac understanding
  • Automatic deck setup

Projects Overview

Project 1


Prepare a consolidated visually appealing utility of all the macros developed during the course. This “Master” utility can then be used by the attendees to access any of the macros in the future as needed.
  • You will be creating a Master GUI using a Tk for all the codes you have written in the coursework.

Project 2


The scope of the project is pretty broad. We are intent to generate a “Model Report” in excel by asking HyperMesh to write a file containing the necessary inputs. The excel report will also be customized using conditional formatting and other tools in excel. From an industrial perspective, this kind of report comes under the “Right at First Time” (RFT) approach.
