Recording [Aircraft Design Workshop: Fundamentals of Aircraft Aerodynamics] Homework Submission For your homework, your task is to investigate the behavior of drag and lift, and look at velocity and pressure distribution across the wing for different angles of attack (which will be sim…

Hi. I have been trying to correspond the simulation process according to the tutorial here. There are some confusions. In “Forces & Moments” section under ‘Wing’, we see that the image contains the value of Write Interval (simulation time steps) is 50, which has not been mentioned below the image, …

Hi @Dhaval ! You can use the write interval of 50 to limit the size of the output. That is absolutely legit here. Regarding your second question I do not know what you mean? @drodriguez32 explained what is to be done in every picture as far as I can see. There are no additional steps you have to d…

Hey @jousefm ! I’m glad for your instant reply. As for the questions I asked my habit of experimenting with the simulation designer has helped me solve all the errors. Indeed the users who are reading these posts must have to go with the images. I’ve shared my homework and have submitted it to the te…

Hi there, My query is with regard with calculating the areas of the projected planes.I downloaded the geometry to find the above values in my cad software,but the file being a .STL file does not show the tree to select individual features and evaluate its properties. Is there any other format whi…

Hi and thanks for this nice instruction. I was able to set up the simulation and I understand the meaning and the purpose to use the symmetry. However I do not completly understand how the results are displayed in the post-processor. Because we are using just half of the model, do we need to doubl…

Hi @Kowalski , indeed the values are half the total force. The force is calculated using the selection, taking no account of the symmetry conditions. Best, Darren

Hi @nsetty and sorry for the small delay. Is there a way you could use another CAD tool? Or did you figure out another solution in the meanwhile? Best, Jousef

Hi, I am running into a ‘Fatal IO error’ around 13 - 18 minutes into my simulation. I have checked the setting and parameters and I am unable to find the cause of error. Moreoever, the error itself is ambiguous and does not point out explicitly to what may have gone wrong. [FATALIO]

Hy @anarayan_das I think the error occurred in your project is due to a bad mesh quality. within the given setup your mesh supposes to have over 9 milion cells with no illegal cells but yours contains only 2 million cells with over 6k illegal faces sown in the screenshot of your project below. you …

Yes,i was able to calculate them using another method.
Thanks
