Hi teachers
Are there any problems with the following sentence?

The initial number of grid planes, lines and points can vary in accordance with the specific requirements such as channel geometry and bottom topographic complexity.

Thanks in advance!

Consider a comma before your "such as" phrase.

Thank you for your help.
I thought there must be something wrong around `such as` initially, but i cannot figure it out myself.

Not if channel geometry and bottom topographic complexity are examples of the specific requirements.
