Dear Otared,

I think there is an issue with the size of math fonts in \frac when used in math alignments, as it is is shown in the following example.

I confirm what you said.

However, if I use \dm{} instead of \displaystyle as following, then the output is correct.

\placeformula

\startformula

\startalignedcases

\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR

\NC \dm{\frac{\partial u}{\partial {\bi n}}}

\NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR

\stopalignedcases

\stopformula

or this (with\type{\displaystyle} added)

\placeformula

\startformula

\startalignedcases

\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR

\NC \dm{\frac{\partial u}{\partial {\bi n}}}

\NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR

\stopalignedcases

\stopformula

In this example, it is OK to use \dm inside of \startformula … \stopformula.

I am not sure that it is what Hans and Mikael want.

Thanks,

Best regards,

Dalyoung
