Pipeline is a safe and reliable mode of transportation and distribution of oil and gas. It is also an economical and dependable mode of transportation particularly to the sensitive and strategic areas where vessels cannot access easily. It provides a long term infrastructural option and solves difficulties in handling large volume of products by rail from one loading point to another and therefore reduces minimum transit loss.

Thank you  for your reply. I know but I was wondering if it is possible to omit them manually.

 One more question, I figured that using *MATRIX GENERATE, one could get the global stiffness, mass or load matrix in a ".mtx" file. But I am wondering why I can't get the file after the run.

Dear friends

I want to plot force-displacement figure for simulation of axial impact in Abaqus;  after using reference points for defining the
displacement and force in tubes and plates , I encounter
two problems:

1)      1)Amount of forces are
negative.

2)      2)I need to filter the figure
because forces have some vibrations in the figure and they are not zero  after rebounding;
they have sine form. So, I have to filter them?

Please let me know how to solve
it.
