  1. Hello dear forum visitors, AFDEX 3D can read AFDEX 2D results files either directly or by means of a simple connecting program, and thus 2D and 3D combined simulations can easily be carried out. Of course, the 2D results can be viewed by the 3D post-processor with more powerful graphics functions. Figure 1. shows the predictions of a five-stage precision cold forging process involving one piercing stage and a final three-dimensional stage, obtained by using the 2D and 3D combined simulation capability with minimum user intervention (i.e., with only an initial run and one connection run). Figure 1: 2D and 3D combined simulation - AFDEX It should be noted that this capability is especially efficient for fastener forming process simulation. The 2D and 3D combined simulation is strongly recommended for enhancing computational time, solution reliability, and engineering productivity when relatively few stages are three-dimensional. So it's time to use your resources smartly. Cheers from AFDEX Support team!
  2. Hello everyone, Let’s assume you have the process design and all the relevant parameters to simulate. So you open a new project in AFDEX, import geometry and define all other simulation factors. This creates .prj, .scf, .sif, .slf and .bat files. Don’t get worried about the new terms. Just have a look at my earlier post (File Types in AFDEX) to get yourselves acquainted. Like any Job Control Language, batch files (.bat) give us the freedom to write our own script so that we can automate the task of running simulations. So after the process definition is over in AFDEX, you can also double click and execute the .bat file to run the simulation. This trick will be very useful if you must execute multiple simulations simultaneously. Please keep following our forum. The next post would probably have an example showing the usage of .bat file to execute multiple simulations in this manner. Following is an example of a effective strain contour from a plate forging simulation executed from the .bat file. Please feel free to ask if you have any questions. Cheers! AFDEX Support Team
  3. Hello everyone, The list of values of state variables like effective stress or effective strain from a metal forming simulation using AFDEX can be easily obtained from the results folder. 1.Navigate to the simulation results folder 2.Open the “element_value.txt” file to view the effective strain and damage values of elements 3.Open the “”node_value.txt” file to view the effective stress and the principal stress values Let us know what you think and feel free to ask questions if you have any. Cheers from AFDEX Support Team!
  4. Hello Everyone, We saw different file types and their meaning in previous posts and the usage of the batch file to execute a simulation. As promised earlier, here is a post that demonstrates how to execute multiple simulations simultaneously. Step 1: Save the simulation files in the same folder. Do not run them Step 2: "Edit" all the ".bat" files as shown in the figure. Step 3: The highlighted first line in every batch file is very important. These lines need to be pasted on a new batch file for simultaneous execution. Step 4: Make a copy of one of the existing ".bat" files like shown in the figure. Step 5: Enter the lines from batch files into the new notepad as shown in the picture. Step 6: Double Click the new batch file to execute the simulations. Let us know what you think and feel free to ask questions if you have any. Cheers from AFDEX Support Team!
  5. Dear Forum users, Here is another example of 2D and 3D combined simulation in AFDEX. The above figure compares the AFDEX predictions with the experiments. This is an automatic four-stage cold forging process for a high-strength bolt. The metal flow lines can also be visualized. Cheers from AFDEX Support Team!
  6. Hello dear Forum users, Below is an interesting simulation result of our AFDEX logo using AFDEX. Cheers from Support team.
