I want to create a flowchart using tikz. My desired flowchart is as in attached figure below.

My questions are:

1. Is it possible to add header to 'container'? I can not create the header


2. I want to increase the length of the line connecting 2 containers. How can I do that?

In addition, I want to increase the arrowhead of edges. I'm not sure how to do that when I'm drawing the edge. The code is attached here.

I want the header of the container something like the the picture below

I think two out of three questions can be answered in a straightforward way.

1. the displacement of the "Microscale Analysis" and "Macroscale Analysis" headers comes from the above right keys, I replaced them by amore appropriate anchors.


2. The arrows library has been superseded by arrows.meta. If you replace latex' by {Latex[length=2mm,width=1mm]}, say, you can make the arrows bigger. (You define the line style twice.)


3. Even though I do not precisely understand what you mean by "I want to increase the length of the line connecting 2 containers. How can I do that?", I just realized that you are not using the positioning library, which makes the relative positioning of nodes a lot easier and more elegant. I changed this. In particular, you will now be able to precisely control the distances between nodes by saying e.g. below=3cm of .... Note the slight but important difference in syntax: instead of below of=... you need to write below=of ... or below=<distance> of ..., where distance is the distance between the node boundaries.


4. I also move the UMAT node at the height of ABAQ and below MatParm.center. This can be done by using (ABAQ.center -| MatParm.center) for its coordinates, see this answer for details.
