  I am trying to mesh an object but I am getting the following error. I have attached the image as well. The surface mesh is intersecting or close to intersecting, making it difficult to create a volume mesh. Please adjust the mesh size or adjust the geometry to fix the problem.

  Much of this part is thin-walled geometry. You might be better off creating a midsurface model and using shell elements.

  there are three ways to solve a thin walled geometry problem right;
  
  shell, solid and solid shell.
  
  for shell method we can use the mid surface method.
  
  How to solve the problem using the remaining two methods?

  Solid elements, just mesh the solid body, but the problem is how to get more than one element through the thickness. To accomplish that, you must slice the part up into sweepable bodies that allow the number of divisions to be set to more than 1 through the thickness. The sweep direction can be either through the thickness or along the length.
  
  Solid Shell SOLSH190 elements require the solid body to be sliced up as above, but with the added requirement that the sweep direction must be through the thickness. That is because the SOLSH190 element must be meshed with the element Z axis in the thickness direction. Regular solid elements don't have a special axis.

  instead of reducing the body into number of divisions can i just reduce the mesh size? For creating number of divisions we will use inflation tool right?

  If you mesh a complex thin-walled body with tet-elements, once the element size is 1/2 the wall thickness, there will be so many elements to fill the volume that the model may not solve in the available RAM or disk space available on the computer. That is why spending a lot of effort to slice the geometry into mostly sweepable pieces allows the volume to be filled in a way that gets more than one element through the thickness without driving the total node count up to a level that won't solve on the computer.
  
  When you have a sweep method, you have a sweep direction, which is where you can define the number of divisions. That is done without using inflation.
