Outlier detection taking lot of time and not giving any results

I am using Automodel feature in Rapidminer educational license version. My processor is 6 core, i7-8750h with 16 GB ram.The dataset have more than 30000 rows and 12 columns . It have numeric and text data both. I tried running using the best features(as detected by Auto model) and am using the distance based outlier method. The model ran for more than 18 hours but still processing. 
I have installed the outlier detection extension too still it didn't help.
How can I solve this issue?  Is it because the educational version uses only 1 core? 
Kindly help
