How to apply pressure field in Nastran
How to apply pressure field in Nastran
(OP)
I have a excel sheet in which there is radius and pressure acting on radius. I have divided the radius in small parts and each part has pressure acting on it. The pressure is like increasing from low to high. Its not uniform.So at every new node new pressure.
I need to apply the pressure on my model in NX. How to do so.Please help me

RE: How to apply pressure field in Nastran
Fortunately it's not necessary to do all this manually. Your preprocessor software is sure to have an option for defining pressure fields. Such an option lets you select the loaded elements and a values table (or equation) that defines the pressure field. Subsequently the preprocessor takes care of generating the correct PLOADx cards for Nastran.

If you are using NX as the preprocessor, then click on the pressure load icon.
In the pressure dialog box, click on the circled location to launch a table input.
At here, you have tonnes of option to input the tabular data. My suggestion is you need to create a new local cylindrical coordinate system in your simulation model, which is referring to your excel data. Based on this reference, choose Domain as Cylindrical, and input your excel data in the form of radius, theta, and z, which is referring to the local cylindrical coordinate you have created earlier.
Also in NX, we have the button to sync excel data, edit the data to NX from excel. Hope this helps.

I tried to import excel sheet also but its not working.Nothing happens.All the field remain blank.I choosed independent of time.

You will need to choose spatial from the pressure drop down list.

For example lets say I have 46 mm radius and I divided it in 14 degrees and every degree has pressure. I added the photo of it. In picture 46 is the radius and 0-14 are degrees and pressure for each degree.

For each data, you need radius, theta, and Z input. So input your sets of values in Excel. And take note, this data set is referring to the cylindrical coordinate system that you defined in NX earlier.

The values that I posted in the above post as screenshot.
RE: How to apply pressure field in Nastran
(same radius, theta1, Z1)
(same radius, theta2, Z2)
