Hello,  
The following code using movemesh returns an error on FreeFEM 4.4 and 4.5 (Ubuntu 18.04):  
//  
load “msh3”  
load “tetgen”  
mesh3 Th = cube(1, 1, 1);  
Th=movemesh(Th,transfo=[x+1,y,z]);  
//

the error message is:  
Th=movemesh(Th,transfo=[x+1,y,z]) error operator (   
List of choices  
( : , \<7E\_Array\>… )  
( : , \<7E\_Array\> )  
( : , \<7E\_Array\> )  
( : , \<7E\_Array\> )

Best regards,  
Laurent

Thank you!  
I am sorry I didn’t check the documentation on “movemesh” before, but I found the wrong syntax in the documentation, in the example for “movemesh23” command, at line 63:  
“meshS Thmv2 = movemesh(Thfinal, transfo=[mv2x, mv2y, mv2z], facemerge=0);”

Best regards
