When I run PDFLaTex when using \tikzexternalize, for large files I get an error that the TeX capacity is exceeded (enlarging does not help). However, when I compile with LuaLaTeX it works (for small tikz files, compiling with PDFLaTeX works fine). If I use \tikzexternaldisable for the large tikz files, then PDFLaTeX also works fine, but then no PDF of the figure is created. Now I want to compile with PDFLaTeX, and only compile the external tikz figures with LuaLaTeX, how can I realize this?

In my preamble is use:

\tikzexternalize[shell escape=-enable-write18]

  {\tikzset{external/force remake=true}\input{Images/#1}}

Then it is working when compiling with LuaLaTex. I added the following to my preamble to run my file with PDFLaTeX:

\tikzset{external/system call={lualatex -enable-write18 -halt-on-error -interaction=batchmode -jobname "\image" "\texsource"}}

I also added --enable-write18 --shell-escape in the command line. Then I tried to run it with PDFLaTeX, but I still get the memory error. How to resolve this?

In my document I use the following to insert the figure (created with Matlab2tikz):

    The first step is to make a complete example that other can tests. Snippets are evil ... – Ulrike Fischer Aug 2 '17 at 8:15
  • I find that creating a graph in a separate file using the standalone document class is more convenient than externalizing graphics. – JPi Aug 2 '17 at 9:46
  • @UlrikeFischer The problem is that when I use a simple example, compiling with PDFLaTeX works fine. Only for large tikz files I have this problem. – Bas Aug 2 '17 at 10:00

    I didn't write "make a simple example" but "make a complete example". Such issues must be tested. So completeness is necessary, simplicity is a bonus. You could try to compile once with lualatex to get the pictures and then remove the external/force remake=true and fall back to pdflatex. – Ulrike Fischer Aug 2 '17 at 12:06
