An example for Dload subroutine in Abaqus
HTML-код
- Опубликовано: 21 авг 2024
- Here an example of the Dload subroutine in Abaqus is provided. Here, a constant circular shape load is applied on a plane. The plane is fixed from the edges and because of the load you can see it bend from the middle section. In addition, in the PowerPoint file, you can find good information about the subroutine code. If you think you need more background it might be a good idea to see the other video about the subroutine.
Using the Dlaod subroutine allows you to apply load with different distribution which can be dependent on the geometry of part and time as well. To use subroutine we need to use FORTRAN code and also Abaqus needs to be linked to Intel FORTRAN. The video is short so you can learn this in less than 15minutes

In this code if we keep the NLGEOM on do we need to add something in Subroutine or leave it as it is? How can we use this code in Moving load?
The time(2) for the second point is 2.5 not 3.5 as mentioned in the video at 2:25
Yes it was a mistake,
Thank you for your comment.
I am not fully understanding the circular area command. Why does load is only applied on centre of the shell geometry?

@@hyperlyceum60 Okay NP
What does characters*80 shows in this subroutine?
Hi, I followed it and didnt get the same results. I even changed the formulation to 3D stress and changed the part to a solid one and I have the same bad result…some stress in one of the corners and thats it. but thanks for the videos, i will keep trying!

Same thing happened to me, when i change the x**2 + y**2
@@civilacademia3831 I think that the equation that is used is not ok. I tried the tutorial twice and made other tutorial with the same subroutine and a different script and it did work. So im sure that is the problem.
@@civilacademia3831 thanks!
@@luzaguilar2139 Well may be, but how is his equation working lols. I play with it and change it into x*y
Can you model UMAT for concrete?
Hi,
Probably,
Because I have already many video requests and I need to create them first.
@@rezatangestani2742 Thank you sir! I have one but i am nerd in Fortran programing it has some compilation error. if i share with you will you be able to check it? i am debugging it and in one line it has some issue it shows error. My email; tufail_mabood@yahoo.com
@@rezatangestani2742 It would be great if you keep updating this video series with more Sub Routines.
@@civilacademia3831 Hi,
No worries,
He will be contact you shortly.
@@hyperlyceum60 Thank you so much for your kind response!
If I want the load to vary with time, is it possible to use the Dload subroutine?
Yes, You can.
you can use time(1) or time (2) (I have explained the difference in the video) to control time.
For example, if you need to decrease the load by time (your step time should be 1 second):
F=F*(1-(TIME(1))
