How to delete a meshed area 1

[bridgehl]

Hi all,

I generated many shell elements from an area. Now, I want to modify only several coordinates of the nodes attached to the area. Ansys does not allow to do that, so I want delete the meshed area but retain the elements to modify the coordinates.

It is possible to do that?

Many thanks,
Bridge

You need to have a keypoint where you want the nodes to be. This means you will have to divide your area up into other areas.

I'm not sure this would be the quickest/best way to do it, but you can try the following:

- create the mesh based on the area

- export the finite element information (either using the CDWRITE command - CDWRITE,DB,file_name,CDB,,, - or going to Preprocessor -> Archive Model -> Write and selecting DB - All finite element information under Data to Archive)

- clear and start a new session

- import the data you saved before by either using the /INPUT command or going to File -> Read Input from.

Once done so, you will have the elements and the nodes you have previously defined but the geometry the mesh was based on won't be imported letting you change any coordinates you want.

Also, being the archived file actually a list of the commands needed to recreate what you had archived, by simply accessing the file with any text editor you can apply any change you want (for example, by changing the coordinates of the nodes you can effectively move them - mind that the NBLOCK command requires the data to be formatted in a very specific way). Of course if you were to do so it is recommended to keep a backup copy of the archived data.
