Hi Mikael,

Thank you for your reply. When I typeset the example you sent me, that is

%begin 240117-1-bis.tex

\definemathsimplealign[alignedcases]
		[left={\startmathfenced[cases]},
		right=\stopmathfenced,
		align={1:right,2:left,3:left},
		strut=yes]

\setupformula
  [location=left]

\starttext

\samplefile{knuthmath}

\startplaceformula
	\startformula
		\startalignedcases
			\NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0      \NC \mtext{bla bla bla}     \NR
			\NC u(x,0)                                   \NC = u_0(x) \NC \mtext{bla bla}         \NR
      \NC u(t,\sigma)                              \NC = 0      \NC \mtext{bla bla bla bla} \NR
		\stopalignedcases
	\stopformula
\stopplaceformula

\samplefile{knuthmath}

\startplaceformula
	\startformula
		\startalign[location=packed,n=2,m=2,align={1:right,2:left},fences=cases]
			\NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0      \NC \NC \mtext{bla bla bla}     \NR
			\NC u(x,0)                                   \NC = u_0(x) \NC \NC \mtext{bla bla}         \NR
      \NC u(t,\sigma)                              \NC = 0      \NC \NC \mtext{bla bla bla bla} \NR
		\stopalign
	\stopformula
\stopplaceformula

\samplefile{knuthmath}

\stoptext

I get something different than the PDF you sent me: the formulas run into the text just above them, as you can see in the attached PDF. I am using ConTeXt LMTX version 2024.01.08 on MacOS 11.7.10. I don’t see what is wrong with my installation…

Best regards: Otared
