Is there a way to avoid the output of the `solve` function? Currently I get the message `Solving linear variational problem.` every time I call `solve(...)`. In my time-stepping procedure I have to call `solve(...)` very, very often within a single timestep and therefore it would be helpful to avoid the output.

What is the `log_level` that you have set in your program ? If you haven’t, you could do something like

```auto
set_log_level(50)

```

or

```auto
set_log_active(False)

```

Of course this assume that you have imported `dolfin` using the wildcards

```auto
from dolfin import *

```

Generally, the lower the `log_level` the more verbose `log` you see in the output. You could experiment with different levels to see what suits you the best in case if you do not want to completely turn it off.
